Expertise and Research Interests
The interests of our lab are on the function/structure of the T cell coreceptor CD8 and characterizing immune responses to Chlamydia Trachomatis.
CD8 Co-Receptor:
1) Ligand Interaction. We are determining the structural basis of how CD8ab interacts with MHC class I by both mutagenesis studies and NMR analysis.
2) The CD8b gene is alternatively spliced resulting in 4 isoforms with different cytoplasmic tails. Differences in function, down-regulation, modification by phosphorylation,ubiquitination, etc are being studied.
Immune Response to Chlamydia Trachomatis (Ct). Chlamydia trachomatis is the leading cause of bacterial sexually transmitted disease worldwide and of preventable blindness in the developing world. We are studying host-pathogen interaction by infecting human trophoblast cells with Ct and monitoring changes in chemokines/cytokines. We are also determining if a set of genes in the Ct genome encodes a typeII-like secretion system that may be important for lateral gene transfer.
