Well-established, regular exercise interventions for older people living with HIV (OPLWH) are beneficial. However, the fundamental principles of exercise prescription for this population have not been sufficiently explored. An expert panel of health care professionals engaged in a modified Delphi technique to explore their perceptions of, and gain their consensus on, an exercise prescription framework for OPLWH in a resource-poor South African setting.

With the evolution of treatment options, there is an increasing interest in the development of long-acting injectable formulations of antiretroviral drugs. These formulations present a promising alternative to oral ART.

Exposure to pulmonary tuberculosis (PTB) culminates in heterogeneous outcomes, including variation in Mtb antigen-specific interferon-gamma (IFN-γ) T-cell responses. IFN-γ-independent cytokines, including tumor necrosis factor (TNF) and interleukin (IL-2), offer potential diagnostic improvements and insights into pathogenesis. We hypothesized that ESAT6/CFP10 TNF and IL-2 responses improve Mtb infection detection among exposed household contacts (HHCs) and are associated with index case Mtb aerosolization (i.

Several strategies have been developed in recent years to improve virus-like particle (VLP)-based vaccine production processes. Among these, the metabolic engineering of cell lines has been one of the most promising approaches. Based on previous work and a proteomic analysis of HEK293 cells producing Human Immunodeficiency Virus-1 (HIV-1) Gag VLPs under transient transfection, four proteins susceptible of enhancing VLP production were identified: ataxia telangiectasia mutated (ATM), ataxia telangiectasia and rad3-related (ATR), DNA-dependent protein kinase catalytic subunit (DNA-PKcs), and retinal rod rhodopsin-sensitive cGMP 3',5'-cyclic phosphodiesterase subunit delta (PDEδ).

Despite advances in medicine and antimicrobial research, viral infections continue to pose a major threat to human health. While major strides have been made in generating vaccines and small molecules to combat emerging pathogens, new modalities of treatment are warranted in diseases where there is a lack of treatment options, or where treatment cannot fully eradicate pathogens, as in HIV infection. Cellular therapies, some of which are FDA approved for treating cancer, take advantage of our developing understanding of the immune system, and harness this knowledge to enhance, or direct, immune responses toward infectious agents.
