Mycoplasma molecular mimicry may be involved in the pathogenesis of AIDS. Antigen similarities between the surface components of pathogenic mycoplasmas and HIV-1 have led to speculation that they use similar mechanisms for cell entry. Interestingly, the HIV‑1 gp120 envelope glycoprotein and M. genitalium adhesin proteins share sequence homology and also have significant similarity with the CD4-binding site of the class II major histocompatibility complex (MHC) proteins. The interactions of pathogenic mycoplasmas with MHC-related antigens on host cells could contribute to a number of possible outcomes, including T-cell dysfunction, T-cell depletion, T-cell shift, B-cell proliferation, hyperglobulinemia and antigen-presenting cell dysfunction. All of these have been observed during the development and progression of HIV-AIDS.
