Thymosin alpha 1 and HIV-1: recent advances and future perspectives
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This review (species not specified) discusses thymosin alpha 1 in HIV-1 infection. It notes that despite benefits of antiretroviral therapy for HIV-1 infected patients, complete immune reconstitution is usually not achieved, and therapy may be accompanied by immunological unresponsiveness, persistent inflammatory conditions, and inefficient cytotoxic T-cell response. The abstract describes thymosin alpha 1 as a thymic peptide reported to restore immune system homeostasis across conditions including infections, cancer, immunodeficiency, vaccination, and aging, acting depending on the host's inflammatory or immune state. The review summarizes in vitro and in vivo studies on thymosin alpha 1 use in HIV-1 infection and discusses findings and future directions for therapeutic intervention.
Abstract
In spite of the consistent benefits for HIV-1 infected patients undergoing antiretroviral therapy, a complete immune reconstitution is usually not achieved. Actually, antiretroviral therapy may be frequently accompanied by immunological unresponsiveness, persistent inflammatory conditions and inefficient cytotoxic T-cell response. Thymosin alpha 1 is a thymic peptide that demonstrates a peculiar ability to restore immune system homeostasis in different physiological and pathological conditions (i.e., infections, cancer, immunodeficiency, vaccination and aging) acting as multitasking protein depending on the host state of inflammation or immune dysfunction. This review reports the present knowledge on the in vitro and in vivo studies concerning the use of thymosin alpha 1 in HIV-1 infection. Recent findings and future perspectives of therapeutic intervention are discussed.
