“Data from the literature have shown that anti-TNFα monoclonal antibodies reduce host defence in various clinically relevant intracellular infection models”
Human TCR: staining of mononuclear and stromal cells and vascular smooth muscle, consistent with TNF-α distribution
“Consistent with the known distribution of TNFα, reactivity was observed with mononuclear and stromal cells in most tissues as well as in smooth musculature associated with vascular walls or selected muscle bundles in a number of tissues.”
Increased susceptibility to infections from long-term TNF-α inhibition
“Since TNFα plays an important role in the defence against various infections, long-term inhibition of TNFα may be associated with an increased susceptibility for infectious disease.”
In vitro whole-blood cytokine release far below alemtuzumab/TGN1412 controls; no effects on monkey TDAR, lymphocyte subsets or serum cytokines; ADA in some monkeys
