Research Interests:

Iron is essential micronutrient for all the organisms because of its ability to function as a protein bound red-ox element. Defective regulation of iron homeostasis leads to either, iron excess and related tissue injuries due to iron-stimulated oxidative damage or iron deficiency disorders. Alterations of iron pool are implicated in tissue injury, diabetes and obesity, cancers, neurodegenerative diseases, inflammation and infections. Prof. Mukhopadhyay’s research interest includes understanding the role of iron in insulin resistance and related disorders, neurodegenerative diseases like Parkinson’s disease. He is also interested in unravelling mechanisms by which protozoan parasite Leishmania donovani alters iron homeostasis in macrophages for its survival and growth, His recent research interest extends in understanding the role of iron and reactive oxygen species in inflammation of macrophages and microglia.

Research Interests:


Molecular and Cellular Endocrinology with focus on Nuclear Receptors

The Nuclear Receptor super-family is a large group of ligand-modulated transcription factors with 48 members presently identified in the human genome. Members of this family of receptors are involved in regulation of numerous physiological and patho-physiological processes and have enormous potential as targets for the treatment of diseases such as cancer, diabetes, coronary heart disease and asthma. Nuclear Receptors, that include steroid hormone receptors, are intra-cellular transcription factors which regulate gene expression in response to their cognate ligands. They function either as homodimers or as heterodimers with retinoid X receptor (RXR). NRs are attractive targets for drug discovery because their activities can be modulated by interacting ligands and have proved to be ‘drug-responsive’. However, some newly discovered members of this family of receptors remain incompletely understood, both in terms of physiological roles and activating ligands. In brief, nuclear receptors represent enormous potential for drug discovery and are continuously being examined to unravel the mysteries underlying their mechanisms of actions. Towards better understanding of the functional significance of these transcription factors some of the comprehensive research projects are in progress in our laboratory. The role of two key xenobiotic receptor i.e. Pregnane & Xenobiotic Receptor (PXR), Constitutive Androstane Receptor (CAR) in metabolism and clearance of endogenous metabolites and xenobiotics (including prescription drugs) and the role of androgen/estrogen receptor mediated signaling in prostate/breast cancer progression are under investigation. In addition to above research interests, mitotic genome-bookmarking by nuclear receptors highlighting a novel dimension in epigenetic reprogramming and disease assessment has been part of an emerging concept initiated from our laboratory.

Professor Suman Kumar Dhar



Prof. Suman Kumar Dhar carried out his doctoral studies (1992-98) from the School of Environmental Sciences, Jawaharlal Nehru University, New Delhi working on replication and maintenance of ribosomal DNA circle in the protozoan parasite Entamoeba histolytica. Prior to joining the Special Centre for Molecular Medicine, he worked on mammalian DNA replication as post-doctoral fellow (1998-2001) at the Brigham and Women’s Hospital, Harvard Medical School, Boston, USA.


Research Interests:


Prof. Suman Kumar Dhar at the Special Centre for Molecular Medicine, JNU is studying replication and cell cycle control of two medically important human pathogens: Plasmodium falciparum that causes human malaria and Helicobacter pylori that causes gastric ulcer and gastric adenocarcinoma. Both these pathogens are immensely important but their biology is poorly understood. Disease control is hampered due to drug resistance and non-availability of vaccine. His main aim is to understand the complex DNA replication and cell cycle mechanisms in these pathogens with a view to identify novel targets for therapy.

His laboratory discovered a mechanism by which the unique DnaB helicase ring is loaded in H. pylori oriC without the use of DnaC, conventional helicase loader, when he identified Hp0897, an unknown ORF as the helicase loader in H. pylori. Further research from his laboratories has shown unique polar replisome and divisome assembly in H. pylori that leads to asymmetric growth of these pathogenic bacteria.

Multiple rounds of DNA replication take place during the blood stage developmental cycle of P. falciparum where 1N DNA content goes up to 16-32 N. Dr Dhar is studying the control of both organellar apicoplast DNA and nuclear DNA replication. He has functionally characterized key molecules that are essential for nuclear/organellar DNA replication. He has also discovered the presence of ARS-like DNA sequences in the Plasmodium genome and identified genome-wide distribution of replication initiation sites in these parasites. The presence of high frequency replication initiation sites in Plasmodium genome may explain the faster cycles of DNA replication in this deadly pathogen.

Using Chemical Biology approach, his laboratory has identified potent inhibitors against H. pylori and P. falciparum that has led to US and Indian patents.


Ongoing Projects:

  1. Deciphering functional role of human pathogenic bacteria Helicobacter pylori arginine decarboxylase; funded by Indian Council of Medical Research, India (2023-26).

The above proposal aims to understand the role of H. pylori arginine decarboxylase in acid response/adaptation and DNA replication leading to the possibility of using it as a therapeutic target against H. pylori

  1. Studies on replication and cell division of two medically important human pathogens Helicobacter pylori and Plasmodium falciparum: unique biology and finding targets for intervention; funded by Sir J. C. Bose National Fellowship, SERB, DST, Govt of India (2021-26).

Studying the H. pylori replisome and cell divisome and their coordination in the context of mammalian host cells will help to shed some insight into the interaction between the host and pathogen. These insights will have possible applications in managing H. pylori infections as inhibition of DNA replication and cell division indeed will have effect on bacterial growth and multiplication. Studying functional aspects of selected Plasmodium falciparum parasite proteins like PfORC, PfMCM, PfPCNA, PfGCN5 etc will not only help to understand the unique aspects of parasite biology ranging from parasite DNA replication, intracellular trafficking to gene regulation, it will also help to establish new target for therapy.

The major objectives of this research group are as follows: 1. To study the role of host ICAMs in cell invasion by Mycobacterium tuberculosis and Plasmodium falciparum. 2. To discover new molecules for TB therapy. 3. To focus on the emergence of Plasmodium falciparum resistance and the repurposing of existing drugs against artemisinin-resistant Plasmodium falciparum. 4. To discover de-novo peptide binders against target proteins of Mycobacterium tuberculosis, Plasmodium falciparum, and Leishmania donovani.

Title: A multi-targeted approach encompassing fundamental and applied studies towards drug discovery for Leishmaniasis

Leishmaniasis is one of the major neglected tropical diseases, for which no vaccines exist. Chemotherapy is hampered by limited efficacy coupled with development of resistance and other side effects. The Leishmania-macrophage interaction provides an excellent example of co-evolution that promotes parasite survival and causes diseases. Conceivably, interfering with these processes represents a promising new strategy against Leishmania. For this, a multi targeted approach is required to get better understanding of these host pathogen interactions to develop a drug. Thus, we proposed to target four essential mechanisms of its pathogenesis to block motility, invasion, growth, sustenance inside the host macrophages.

Professor Shailja Singh



Shailja obtained her PhD in Biomedical Sciences at the University of Delhi. During her post-doctoral tenure at the International Centre for Genetic Engineering and Biotechnology (ICGEB) in Delhi, she was awarded multiple international accolades, including the Bill & Melinda Gates Foundation Travel Award for attending malaria conferences. Thereafter, Shailja joined the Department of Life Sciences at Shiv Nadar Institution of Eminence (SNIoE) as an Associate Professor, where she received prestigious awards such as the Innovative Young Biotechnologist Award (IYBA) from the Dept. of Biotechnology (DBT), Govt. of India, and the Shiv Nadar University Award and Indus Foundation Award for Research Excellence. In 2016, Shailja joined the Special Centre for Molecular Medicine, Jawaharlal Nehru University, Delhi, and successfully progressed towards attaining the position of a full professor. In recognition of her translational research in Malaria and Kala-azar, Shailja has been honored with various prestigious awards, including the Women Bioscientist Award from DBT and the Biotechnology Industry Research Assistance Council-Gandhian Young Technological Innovation Award (BIRAC-GYTIA) from the Honorable President of India. Shailja currently serves as an expert member in several regulatory bodies within the university and the Govt. of India. With 25 years of research experience, her expertise lies in molecular parasitology, focusing on understanding host-pathogen interactions in diseases like malaria and Kala-azar. Scientific contributions from Shailja’s lab have been published in esteemed peer-reviewed journals, including Nature Communications, EBioMedicine, Proceedings of the National Academy of Sciences (PNAS), Advanced Healthcare Materials, and Cell Death Discovery, among others.


Research Interest:

Shailja exemplifies a highly successful homegrown scientist in India. Her research group focuses on understanding the fundamental and medicinal aspects of human malaria and leishmania parasites. She pioneered the identification of signaling molecules (Ca2+ and cAMP) and signal transduction pathway effectors (CDPK1, CN, PAP, DGK, PAT, PLPs, etc.) involved in malaria parasite invasion and egress. This groundbreaking work has paved the way for innovative anti-malarial medications. Shailja’s research group has significantly contributed to translational research, particularly in anti-malarial and anti-Leishmanial inhibitor screening and development. Recognized by Biotechnology Industry Research Assistance Council (BIRAC)-Gandhian Young Technological Innovation (GYTI) awards, she has developed breakthrough drug discovery tools. Furthermore, she introduced a nanomedicine-based approach using surface-coated iron-oxide-nanoparticles to enhance the efficacy of the age-old anti-malarial medication, Artesunate. In collaboration with Institut Pasteur, France, she discovered that the patatin-like phospholipase that regulates gametocyte egress has the potential to prevent malaria transmission. Notably, her recent discovery of a host erythrocyte micro-RNA, miR-197-5p, revealed an unusual, nucleotide-based therapy and inspired a novel strategy for generating anti-malarial molecular pharmaceuticals. Her research group has also identified several parasite chaperones, such as Prefoldins, Cold shock protein, and Prohibitins, while exploiting host proteins like SphK1, HSP-70, PMCA4, G6PD, LanCl2, Kell, and NMDA for antimalarial drug development.


Ongoing Projects

1. Title:
“Evaluation of the role of S1P in Tribal Plasmodium falciparum malaria patients for its potential therapeutic consideration”
Brief abstract:
This project aims to establish the role of Sphingosine-1-Phosphate (S1P) in severe human malaria of various clinical manifestations, particularly in adult patients. Besides, the study will investigate whether genetic variations in the S1P pathway contribute to the clinical severity of malaria. Further, it will also explore the influence of S1P on critical pathogenic processes in severe malaria, such as endothelial dysfunction, inflammation, and NO production. Overall, the findings will provide clues for the prognostic implication of S1P in severe P. falciparum malaria and could support its use as an adjunctive therapeutic in severe malaria cases.

2. Title:
“A comprehensive characterization of key organellar metabolic transporters in Apicomplexa to enter in the drug discovery pipeline”
Brief abstract:
This research addresses the critical need for the development of novel and effective antimalarial compounds with limited off-target effects. Surprisingly, there is little redundancy in the Plasmodium 'Transportome' and substantial evidence that membrane transporter proteins are likely to serve as therapeutic targets. Our integrative strategy, which combines biochemical, biophysical, and molecular approaches, will allow us to identify small molecule candidates against the transport of mono-carboxylates, which is critical for parasite survival. The ultimate goal of the project is to determine whether these transporters have antimalarial, transmission-blocking, or preventive potential.

Dr. Souvik Bhattacharjee, Associate Professor


Dr. Souvik Bhattacharjee carried out his doctoral studies the CSIR-Institute of Microbial Technology, Chandigarh. He pursued his research work in the area of ‘Protein trafficking in malaria-infected erythrocytes and the mechanism of artemisinin-resistance’, firstly as a post-doctoral fellow at Northwestern University, Chicago, and then as Research Assistant Professor at the University of Notre Dame, Indiana. Prior to joining the ‘Special Centre for Molecular Medicine’ in 2015, he was working in artemisinin-resistance mechanisms Plasmodium falciparum at the University of Notre Dame, USA.

Research Interest:

The research in my laboratory is directed towards the elucidation of targeting signals that sort proteins destined for localization within the different compartments in the host-pathogen interface. Primarily, we are looking in Plasmodium falciparum as the human pathogen, and Phytophthora infestans as the plant pathogen. We trace the evolutionary convergence in the virulent protein trafficking mechanisms across pathogens of different origin and we characterize essential motifs using transgenic approaches.  Our other area of interest involves understanding the contribution of host factors towards the development of artemisinin-resistance in P. falciparum.


Ongoing Projects:

  1. Translating the Phylogenetic affinities between a plant pathogenic oomycete Phytophthora infestans and a human pathogen Plasmodium falciparum to reveal evolutionary convergence in virulence secretion using in-silico, proteomic and metabolomic approaches. (DST-SERB CRG/2021/000238).
  2. Elucidating the role of clinical anemia in the induction of artemisinin resistance in Plasmodium falciparum. (ICMR; 58/25/2020/PHA/BMS).
  3. Unravelling the molecular mechanisms underlying human ABO blood type preference by the virulence RIFIN variants in Plasmodium falciparum-infected erythrocyte rosettes. (MoE STARS Project ID: 2023-0111).

Dr. Saima Aijaz, Assistant Professor


Dr. Saima Aijaz received her Ph.D degree from the Indian Institute of Science, Bangalore, India where she worked on the outer capsid protein of rotavirus to evaluate its potential as a recombinant vaccine candidate. During her post-doctoral work at University College London (United Kingdom), she worked on the functional characterization of proteins associated with epithelial tight junctions. After joining SCMM, Dr. Aijaz started investigating the effect of tight junction disruption on the pathogenesis of intestinal infections caused by Enteropathogenic E. coli as well as in rare diseases such as retinitis pigmentosa type 12.


Research Interest:

1. Regulation of the tight junction barrier in Enteropathogenic E. coli infections
2. Disruption of the Tight Junctions in Retinitis Pigmentosa Type-12

Tight junctions seal adjacent epithelial cells to selectively regulate paracellular permeability and prevent the intermixing of apical and basolateral proteins of the plasma membrane. Regulation of paracellular permeability is a critical function of tight junctions and increased permeability is associated with diverse disease conditions ranging from bacterial and viral infections to cancer and metastasis. Research in the laboratory is focused on the molecular mechanisms that regulate the disruption of tight junctions in epithelial cells in response to pathologic stimuli. In one approach, Enteropathogenic E. coli (EPEC) is used as a model system to study the regulation of paracellular permeability. EPEC disrupts epithelial tight junctions and is a leading cause of diarrhea in the developing world causing significant morbidity and mortality due excessive permeability of water and electrolytes through the intestinal tight junctions. However, the underlying mechanisms that cause the drastic increase in permeability through intestinal junctions have not been elucidated yet. The laboratory is engaged in the identification of tight junction-based signaling pathways that regulate the EPEC-mediated leakage through tight junctions with the ultimate goal of identifying molecules to block/reverse this leakage. In another approach, work is being carried out to understand how defects in the tight junctions of retinal pigmented epithelia prevent the normal functioning of the retina in retinitis pigmentosa type 12.


Ongoing Projects:

1. Restoration of the intestinal barrier in Enteropathogenic E. coli infections: Lysosome and cytoskeleton pathways as novel drug targets (PI). (2020-2024). Funded by MHRD-STARS

The aim of this project is to identify whether modulation of the host cell lysosomal machinery can prevent leakage through intestinal tight junctions.

2. Mechanisms of retinal degeneration in Retinitis Pigmentosa Type 12: Role of the Crumbs homology proteins-1 and -2 (PI). (2020-2023). Funded by ICMR.

This project is designed to understand how defects in the Crumbs homology proteins-1 and -2 cause retinitis pigmentosa type 12.

Dr. Dipankar Ghosh, Assistant Professor



Dipankar Ghosh carried out his doctoral studies in Jadavpur University, Kolkata. He pursued his postdoctoral research in Immunology and Infectious Diseases in the Cleveland Clinic, Ohio USA, where their group discovered the post-translational processing and functions of human defensin 5 (HD5) in innate immune response. For this he won the Berlin Bumpus Investigator award in the USA. Subsequently he worked in the Indian Institute of Technology (IIT), Kharagpur, before joining SCMM.


Research Interests:

We work on early host-microbe interactions, that ultimately define the predisposition and/or outcomes of diseases. The human epithelial surface is continuously exposed to microbes. This epithelium presents the first line of defence against external threats. This defence is not physical barrier alone; but extremely complex array of receptors, signalling cascades and effectors that are key to innate immunity.  We are interested to understand how epithelial and innate immune cells interact with themselves and bacteria to exert this innate immunity. For this we study nutrition, microbiota and biofilms with specific emphasis on Quorum signalling and the cross talk with innate immune determinants. These studies help to contribute to the understanding of lethal multiple drug resistant nosocomial infections and sepsis, especially neonatal sepsis which kills thousands of babies in early life. We are currently part of the National Neonatal Sepsis Research Consortium (DBT), one of the largest research programs in India in collaboration with AIIMS, TSHTI, IGIB, NII and ICGEB.
