Abstract

In this work we demostrate that IgA purified from HIV infected patients recognizes a band with a molecular weight corresponding to radiolabelled ileal muscarinic acethylcholine receptors (mAChR) by immunoblotting. HIV+-IgA triggers the signals that are the consequence of mAChR stimulation in the intestine, regulating protein kinase C (PKC) and nitric oxide synthase (NOS) activity as well as 3',5'-cyclic guanosine monophosphate (cGMP) formation. On the one hand PKC activation by HIV+-IgA induces NOS inhibition and as a consequence, low amounts of NO that could improve local immunosuppression in the intestine; on the other hand HIV+-IgA stimulates cGMP production which could potentiate ileal motility and loss of water/electrolytes involved in intestinal damage in AIDS.
