 • Host-Pathogen interactions and immune evasion mechanisms (MC 205 (AUG) 2:0)

This course will utilize multiple host-pathogen pairs as models to demonstrate the innumerable mechanisms utilized by pathogens of viral, bacterial and parasitic origin to subvert the host and enhance their own survival. Secretion systems of bacteria: Type I, II, III, IV V, overview of ABC exporters and importers, plant pathogen interactions, virulence gene expression, intracellular pathogenesis; signaling by the bacterial components; innate and adaptive immunity to bacterial pathogens; quorum sensing, biofilm formation and its role in pathogenesis. Viral immune evasion mechanisms such as functional mimicry of host complement proteins, secretion of chemokine and cytokine-like molecules, inhibition of NF-қB and apoptosis, inhibition of serine proteases of the host antigen presenting cells to suppress antigen presentation, inhibition of MHC class I presentation of viral antigens, inhibition of host secretory pathway, prevention of phagosome acidification, antigenic variation and suppression of TH1 responses by protozoan pathogens, role of host TRIM5 family proteins in controlling HIV by mutation of viral RNA, ds-RNA and non-capped 5’ end mediated recognition of pathogens by the host, will be some of the topics that will be covered.
