There is an intense interplay between HIV and the immune system, and the literature is replete with studies describing various immunological phenomena associated with HIV infection. Many of these phenomena seem too broad in scope to be attributable either to HIV-infected cells or to the HIV-specific immune response. Recently, a more fundamental understanding of how HIV affects various T cells and T cell compartments has emerged. This review covers the role of immune activation in HIV immunopathogenesis, how that activation could be mediated directly by HIV replicating within and damaging the gut mucosal barrier, how HIV affects multiple T cell functions and phenotypes, and how chronic HIV replication induces immune modulatory pathways to negatively regulate certain functions in HIV-specific T cells.

Background: The relationship between plasmatic fatty acid (FA) composition and liver fibrosis remains scarce in people living with HIV/AIDS (PLWHA). We aimed to evaluate the association of plasmatic FAs and liver fibrosis in HIV mono-infected individuals.
Methods: This case-control study included PLWHA with liver fibrosis (cases) and randomly selected subjects without fibrosis (controls) from the PROSPEC-HIV study (NCT02542020).

Background: The relationship between tumour necrosis factor (TNF) levels and disease progression is well-established. However, the impact of changes in the level of TNF hydrolase (A-disintegrin and metalloenzyme 17; ADAM17) in HIV patients remains to be fully elucidated.
Methods: Between March 1 and December 31, 2017, data were collected from 64 HIV-positive individuals in Wenzhou.

Background And Objective: Serological screening for Chagas disease (CD) in Latin American adults living in Europe is a cost-effective strategy for transmission prevention. The World Health Organization recommends two different serological tests including native and recombinant antigens for IgG detection. In Spain, most commercialized native tests require manual processing.

Natural products isolated from have attracted considerable attention from the chemical community due to their unique structures and promising anti-HIV activities. Recent progresses in the isolation and bioactivity studies for these natural molecules were summarized comprehensively. From the 23 previously uncharacterized compounds isolated from the plant , litseaverticillol B demonstrated the most potent anti-HIV activity , with IC ranging from 2 to 3 μg/mL.

Objective: The aim of this study was to assess the clinical value of metagenomic next-generation sequencing (mNGS) of blood samples for the identification of disseminated tuberculosis (DTB).
Methods: A total of 48 individuals suspected of DTB were enrolled. All patients underwent mNGS of peripheral blood and conventional microbiological tests.
