Thrombocytopenia is common in HIV and SIV infection, and is often associated with disease progression. HIV and SIV-associated thrombocytopenia arise through multiple mechanisms, including decreased platelet production, increased platelet destruction due to HIV-mimetic anti-platelet antibodies, and increased use of activated platelets. Activated platelets have the potential to contribute to the pathogenesis of HIV and SIV by interacting directly with inflammatory cells and endothelium and by releasing soluble immunomodulatory cytokines.
血小板减少症在HIV和SIV感染中很常见,并且常常与疾病进展相关。HIV和SIV相关的血小板减少症通过多种机制产生,包括血小板生成减少、由于模仿HIV的抗血小板抗体导致的血小板破坏增加,以及活化血小板的使用增加。活化血小板有可能通过直接与炎症细胞和内皮细胞相互作用以及释放可溶性免疫调节细胞因子来促进HIV和SIV的发病机制。
