TLR2 engagement on CD4(+) T cells enhances effector functions and protective responses to Mycobacterium tuberculosis.

abstract：:The cell surface molecule CD44, thought to be a cell surface receptor for hyaluronic acid, is expressed by thymocytes and peripheral T cells. Following T cell activation with mitogens or antigens, surface expression of CD44 increases. This increase in CD44 cell surface expression has been used as a means of identifyin...
