Trypanosoma evansi: Immune response and acetylcholinesterase activity in lymphocytes from infected rats

► Trypanosoma evansi is transmitted to the host. ► Multiply in the skin or mucosa. ► Increase the population and the antigenic diversity of parasites. ► Stimulating the production of B cells and T cells. ► Lymphocytosis. ► Cholinergic receptors in the immune system cells. ► Acetylcholine is involved in the regulation of immune function. ► Acetylcholinesterase. ► Hydrolyses esters with acetyl group (as acetylcholine). ► Change in cholinesterase activity in rats infected with T. evansi. ► Alteration related to immune response. ► Inflammation.
