Research:
- T lymphocyte biology and Tumor Immunology: T lymphocytes express specific antigen receptors and are genetically geared to recognize internal (cancer) or external (pathogen) threats to the body. T cell activation is the first step in generating threat-specific T cell immune response. Activated T cells then rally other immune cells to generate an effective immunity. T cell activation and the responses it orchestrates is highly regulated to ensure no bodily harm caused in battling the threat. Inhibitory proteins expressed on the activated T cells are central in preventing excessive activation and responses generated by T cells. Ly-6A protein, a member of Ly-6 supergene family, contributes to self-regulation of CD4+ Helper T lymphocyte responses in mice. Ly-6A protein shows either no or low expression in naïve CD4+ T cells, its expression is highly upregulated upon T cell activation and in the presence of cytokines (IL-27 and IFN-gamma). In vitro and ex vivo studies provide strong evidence for Ly-6A as T cell inhibitory protein. Our laboratory is currently examining the immune checkpoint inhibitory role of Ly-6A using tumor (B16-F10 melanoma and MC38 adenocarcinoma) transplantation mouse models for potential cancer immunotherapy using Ly-6A-targeted antibody blockade strategy. Additionally, we are investigating how Ly-6A signals to cell interior in the absence of its transmembrane and cytoplasmic tail. Another project in our laboratory concerns the spatiotemporal aspect of cell signaling in CD4+ helper T lymphocytes with the focus on cholesterol-rich membrane nanodomains, also known as lipid rafts. Lipid rafts show high representation of sphingolipids, glycosyl-phosphatidylinsitol (GPI)-anchored proteins (e.g., Ly-6 proteins) and several lipid-modified signaling molecules. These membrane nanodomains are compositionally heterogeneous, dynamic and exist as 10-100 nanometer size structures in a variety of cell types. We have reported that these lipid nanodomains coalesce during interactions between CD4+ T cells with antigen presenting cells. We are currently investigating the role of cholesterol-rich membrane domains in T cell signaling and determining which T cell signal(s) regulate membrane lipid nanodomain coalescence. Additionally, we are examining the role of these membrane nanodomains in delivering signals generated after engaging tail-less GPI-anchored proteins (e.g., Ly-6A).
