Regulatory role of CD19 molecules in B-cell activation and differentiation.

abstract：:Senescence is characterized by several alterations in the immune system. Such modifications can be found in lymphoid organs as well as in the cellular components of the immune system. Several reports have suggested that immune dysfunction can affect both T and B cells, but T cells have been shown to be more susceptibl...
