Skip to main content Development of Mucosal Immunity We study human genetic diversity associated with inflammatory bowel diseases to understand the principal mechanisms of mucosal immunity that control the intestinal barrier function and the microbiome. Immune responses control host defenses intestinal at epithelial interphases.

Skip to main content Microtubule-Based Microbial Pattern Recognition System Cells contain a reservoir of inactive GEF-H1 bound to microtubules that is activated by dephosphorylation to form signaling platforms for the activation of innate and cell-autonomous immunity. Muramyl-dipeptide (MDP) is the minimal structural motif of peptidoglycan of both Gram-positive and Gram-negative bacteria and the functional component of Freud’s adjuvant used to boost vaccination responses. Genome-wide

Protecting Groups in Organic Synthesis-1 Ready Protecting groups are a sad fact of synthetic chemistry They are usually needed, but rarely desired Many syntheses have stalled because of trouble putting on or removing protecting groups 4 basic questions to address when choosing a P.G.: 1. Can I put it on where and only where I want? 2. Can I take it and only it off? 3. Will it survive all future reaction conditions? 4. Will it
