Rahul S. Shinde, D.V.M., Ph.D. 


The Shinde Laboratory



Caspar Wistar Fellow, Immunology, Microenvironment & Metastasis Program, The Wistar Institute Cancer Center

About the Scientist

Shinde is an immunologist with interest in characterizing key factors in the tumor microenvironment and gut microbiome that contribute to the refractory nature of cancer and target them for therapies.

Shinde obtained his D.V.M. from Nagpur Veterinary College, India, and his Ph.D. in immunology from the Augusta University. Before joining Wistar as the first/inaugural Caspar Wistar Fellow, he trained as a postdoctoral fellow in the Tumor Immunotherapy Program at the Princess Margaret Cancer Center in Toronto, Canada.

The Shinde Laboratory

The tumor microenvironment (TME), consisting of stroma, immune cells and extracellular matrix, is a key determinant of cancer initiation, progression and resistance to therapies. Understanding the heterogeneity of the TME and the molecular mechanisms contributing to immune responses is critical to enhance immunotherapy and prevent/overcome resistance. Macrophages are major components of the TME and regulate inflammation, angiogenesis, extracellular matrix remodeling, and T-cell suppression. Alterations in the metabolism of macrophages affect their function. Research in the Shinde lab focuses on characterizing the molecular mechanisms underlying metabolic plasticity in macrophages during tumorigenesis.  

Commensal microbiota residing in the gut can also modulate the TME and affect tumor progression and response to therapy. Host, dietary and environmental factors contribute to changes in the microbiome. The lab is also interested in characterizing the healthy/symbiotic or disease-modulating/dysbiotic microbiome and its crosstalk with immunometabolism during disease development.

Available Positions

A postdoctoral fellow position is available in the Shinde lab. Applicants should have or be close to obtaining their doctoral degree (or equivalent) in biomedical sciences or a related field. 

The ideal candidate will have experience in immunology, cancer biology, macrophage function, mouse modeling, and relevant experience with the gut microbiome. Interested applicants should submit a cover letter summarizing past and future research interests, CV, two references, and reprints of two supporting publications (optional) to Dr. Shinde at


The Shinde lab investigates amino acid metabolism in regulation of immunity. Metabolic profiling has identified increased plasma levels of branched-chain amino acids (BCAA) in a variety of disorders including pancreatic cancer. BCAA are a class of essential amino acids that can influence immune functions and disease outcome. Dietary intake represents a major source for BCAA in the circulation, but it is unclear what contributes to altered levels of BCAAs and their effects on disease onset and progression. 

BCAA metabolism is transcriptionally controlled by Krüppel-like factors (KLFs). KLFs are DNA-binding transcriptional regulators known to control multiple metabolic events including glycolysis, oxidative phosphorylation, fatty acid oxidation, and degradation of amino acids.  Alterations in KLF signalling and post-translational modifications are linked to monocyte differentiation, macrophage polarization, angiogenesis, and inflammation. However, the biologic role of KLFs in tumor immunology is not well understood. Mechanistic and functional characterization of the KLF biology and the BCAA pathway contributing to the altered metabolic state of macrophages will provide significant insight into the behavior of macrophages in the TME. 

The lab is interested in evaluating the functional implications of KLF biology and BCAA catabolism in macrophages driving tumor progression and resistance to therapy. These studies will have potential clinical impact providing insights into previously unsuspected targets for therapy.
