Past Projects

Novel anti-PD-L1-CD3 bispecific T-cell engager (BiTE) antibodies for enhanced cancer immunotherapy

Supervisor: Dr. Yatender Kumar, Netaji Subhas University of Technology

This work contributes to my bachelor’s thesis. I am designing a bispecific antibody having anti-PD-L1 and anti-CD3 domains; anti-PD-L1 domain can inhibit PD-1/PD-L1 pathway and recruit PD-L1+ tumor cells to CD3+ T-cells, which will mount a suitable immune response. The novelty of this work lies in the combination of biomarkers used, increased binding affinity of paratopes with its respective epitopes, and a unique Fc region consisting of a linker between the two epitope binding domains. This linker makes it easier to synthesize our antibody in mammalian systems at cheaper costs.

Structural study of protein-ligand interactions involved in cardiovascular disease to identify novel and efficient inhibitors

Supervisor: Prof. Sonika Bhatnagar, Netaji Subhas University of Technology

My primary role is performing molecular dynamics simulation of protein-ligand interactions to find the best ligand out of a list of ligands, which efficiently inhibits the activity of a therapeutic target playing a significant role in atherosclerosis, a cardiovascular disease, in order to develop an effective drug for its treatment.

Molecular diagnosis of the five human malaria parasite species in a single step polymerase chain reaction (PCR) using a universal primer pair

Supervisor: Dr. Abhinav Sinha, National Institute of Malaria Research (Indian Council of Medical Research)

During my internship in summer 2017, I worked on the optimization of the standard PCR protocol for the identification of Plasmodium sp. and PCR-based detection of mixed infection of P. falciparum and P. vivax in patients attending the Malaria Clinic of NIMR. Now, I am involved in the extension of the project, where currently I am designing an oligonucleotide primer pair that can detect all five human malaria-causing Plasmodium sp. in a single step PCR, thereby reducing labor, capital, and time that is invested in conventional diagnostic methods.

Synthesis and characterization of small molecules for targeting mitochondria in cancer treatment

Supervisor: Dr. Sudipta Basu, Indian Institute of Science Education and Research-Pune (Now, at Indian Institute of Technology-Gandhinagar)

The main objective of the project was to design and synthesize small molecules that can effectively target mitochondria in cancer cells. We repurposed two generic drugs (artemisinin and chloramphenicol), which has demonstrated mitochondrial toxicity; hence, may serve as a cheaper alternative for chemotherapy. We hypothesized that these molecules could easily enter pores formed in tumor tissues post angiogenesis making it specific to tumor cells. The positively-charged TPP moiety will guide the drug to the mitochondrial membrane, which has a higher negative membrane potential than the cell membrane. Now, the drug localized in mitochondria can induce mitochondrial damage, thereby triggering the caspase cascade leading to apoptosis of the tumor cell.
