Scientific Interest(s):

A major research focus in Dr. Ram Raj Singh’s laboratory is the understanding of the mechanisms of dendritic cell migration, the investigation of dendritic cell–gamma delta T-cell interactions and the exploration of how dendritic cell migration can be modulated to enhance the efficacy of vaccination and to suppress autoimmune inflammation using models of lupus dermatitis.

Another major aim of Singh’s laboratory, in collaboration with Arthur Arnold (Physiology) and Rhonda Voskuhl (Neurology), is to understand mechanisms of gender bias in immune and autoimmune response and autoimmune diseases. In particular, Singh and his team are interested in understanding the role of sex chromosome complements in altering immune regulation and inducing autoimmune diseases such as lupus.

Additional research projects involve investigating the homeostatic regulation of marginal zone B-cells by invariant natural killer T-cells, the role of natural killer T-cells in autoreactive T- and B-cell activation and autoimmune disease, mechanisms of T-cell anergy and activation in autoreactive T-cells, biomarkers of autoimmune diseases in lung, kidney and skin disease and the role of mesenchymal stem cells in causing immune aberrations in autoimmune disease models.
