TOLLIP deficiency BCG TNF; IL-6 TOLLIP TLR, 2, 4, 6 T cell differentiation Altered memory response CD4+ T cell Reduced vaccine duration? Increased TB pathology?
SUMMARY A functional single nucleotide polymorphism alters TOLLIP promoter activity in monocytes Antisense RNA TOLLIP-AS influences TOLLIP expression (and perhaps innate immune responses) TOLLIP deficiency is associated with altered T cell phenotypes from a very early age TOLLIP variation is associated with TB in multiple genetic case control cohorts
