Mecp2 Dup mice also showed aberrations in serum and BALF cytokines and chemokines following influenza infection, suggestive of heightened T cell proliferation (IL-2) and tissue recruitment (CCL19), as well as Th1 skewing (IFNγ, CXCL9, CXCL10 and CCL5) and inflammation (TNFα). Here, CXCL10 is linked to influenza.
