Micro-environment mediated regulation of Hematopoietic Stem Cells
Mesenchymal stromal cells (MSCs) form an important component of bone marrow microenvironment. These cells respond to the external cues and modulate the fate of hematopoietic stem cells (HSCs). Extra-cellular vesicles (EVs) comprising of micro-vesicles and exosomes form a very important medium through which the stromal cells communicate with the stem cells. Our aim is to examine the molecular composition of EVs collected from MSCs treated with specific signaling modifiers like AKT inhibitors, ERK inhibitors, NO donors, hypoxia-inducing agents and simultaneously examine the effect of these EVs on the functionality of the HSCs. Since EVs can be effectively cryopreserved, they can be stored as "ready-to-use" reagents for application in clinical transplantations.
Neuronal regeneration using Extracellular Vesicles derived from Mesenchymal Stromal Cells
Neurodegenerative diseases are associated with neuronal loss and neural cell death associated with formation of protein aggregates. A long asymptomatic period before disease manifestation, difficulty in diagnosis, lack of validated animal models, and insufficient understanding of the cause and mechanism are major challenges to study neurodegenerative diseases. Our hypothesis is that EVs collected from mesenchymal stromal cell (MSCs) primed with neurotropic factors would possess neuro regenerative properties. Hence our primary aim is to develop a valid in vitro neurodegenerative model (using neuroblastoma cell line Neuro2a) to examine whether EVs secreted by MSCs primed towards neuronal lineage would rescue the Neuro2a cells from degeneration. A byline would be to elucidate the role of autophagy in neuro regeneration.
Type 2 Diabetes and associated risk factors
The laboratory focuses on understanding the association of different risk factors with Type 2 diabetes. This laboratory is well equipped to perform different techniques related to clinical biochemistry, hematology and immunology. Ongoing projects involve effect of plant extracts on different clinical conditions and association of oxidative stress and inflammation with ageing and vitamin D deficiency in middle-aged type 2 diabetics.
One of the interests in this area is biochemical and molecular characterization of probiotic and industrially important properties of Lactic Acid Bacteria (LAB). Such experiments are performed on the strains obtained from the standard culture collections as well as those isolated in house from various food products. In addition, improvement in certain important features of LAB is also being sought through metabolic engineering as well as adaptive laboratory evolution. These projects are further empowered by genome sequencing and RNA-seq analyses. In a couple of other projects, plant and bacterial β-glucosidases are being characterized by recombinant expression in E. coli for their potential of improving the flavor of fruit products.
Research laboratory is focused on biotransformation of Xenobiotics. In vitro methods are developed to understand the metabolic pathways for pharmaceutical drugs, nanomedicine and environmental pollutants. Analytical technologies are utilized to characterize the structure of metabolites.
Bacterial communication and Host-pathogen interactions
The laboratory focuses on understanding the mechanisms underlying the interspecies bacterial quorum sensing and its role in the regulation of virulence phenotypes, thereby providing a prospective for better therapeutics in order to disable the pathogenesis and identify novel drug targets to combat the antimicrobial resistance.
The BSL-II laboratory is well equipped to perform advanced molecular biology techniques involving cell culture, gene manipulation and transcriptome analysis. Ongoing projects involve identification of molecular mechanisms of interspecies bacterial communication on virulence of Streptococcus pyogenes, understanding the host-pathogen interaction in Neisseria meningitidis and Listeria monocytogenes.
Cellular signalling and molecular cross talks due to glycation amplifies inflammation, microvascular dysfunction and further leads to complications such as nephropathy, cardiovascular diseases. The research interest of the lab is to understand the biochemical pathways of glycation modifications in diabetes and associated secondary complications.
The research may form the basis for the identification of molecular targets for therapeutic treatment or prevention. Another research area of the group is to evaluate the drugs from complementary and alternative therapies and confirm their mechanism of action in control of the diseases.
Avian and bacteria viruses (Bacteriophages) - experimental animal facility
The objective of the laboratory is to identify and characterize isolated virus by classical virological techniques, biological characterization in animal models and molecular characterization. Laboratory is equipped with all the requirements for growing avian viruses in cell culture, embryonated chicken eggs and in experimental chickens. Virology laboratory is allied to centralized experimental animal facility which is registered with Purpose of Control and Supervision of Experiments on Animals (CPCSEA). Lab is equipped and maintained with all the ethical guidelines and following rules and regulations put forth by the CPCSEA.
Ongoing projects in the laboratory involve isolation; characterization and evaluation of lytic bacteriophages form the sewage water against Escherichia Coli and Salmonella spp.
Complex diseases are influenced by a combination of genetic and environmental factors. The emergence of these diseases is therefore difficult to predict. The goal of our lab is to identify markers for diagnosis / prognosis of complex diseases and to provide therapeutic targets using multi-omics data analysis.
The lab holds expertise in areas of genomics and proteomics. The technical expertise of the lab within the genomics field extends to RNA-Sequencing and ChIP-Sequencing data analysis for identification of differentially expressed / alternatively spliced transcripts and for protein-DNA interaction. Genomics expertise also extends to Exome-Sequencing analysis for germline variants and transcriptome assembly and annotation. Proteomics analysis is currently limited to label free quantitation (LFQ). Expertise in bioinformatics is currently limited to database management.
The MACD Lab is keen to provide its services in the form of academic collaborations with joint grant applications as well as consultancy services. The general guidelines followed by us can be found here.
Our immune system is characterized by specific immune response to different immunogenic molecules called as antigens. Such specificity is brought about by the immune cells expressing receptors specific to individual antigenic molecule. Population of immune cells expressing such receptors are known as lymphocytes and consists of B - and T cells. T cell receptors (TCR) are always expressed on the cell surface whereas B cell receptors (BCR) can be found in membrane bound as well as secretory from. The secretory form of BCR is called as antibodies. Antibodies are widely used as diagnostic marker as well as therapeutic biomolecules in many pathological conditions associated with infection, autoimmunity and various cancers. Though immunological techniques for detecting the antigen specific antibodies are available, the tools and techniques for isolating the disease associated (including autoimmunity and cancer) antigen-specific B cells are still not available. Therefore, the focus of my research work is to develop the reagents that can be used for the high throughput isolation and characterization, of antigen specific B cells. The availed information can then be used for the development of diagnostics and/or therapeutics.
Additionally, my research work also focuses on development of nano-carrier based vaccine platforms and the study of immunomodulatory effects of probiotic bacteria, bacteriophages and natural compounds. The list of my publications can be found here.
