Background: C-X-C chemokine receptor type 5 (CXCR5)CD8 T cells represent a unique immune subset with dual roles, functioning as cytotoxic cells in persistent viral infections while promoting B cell responses. Despite their importance, the specific role of CXCR5CD8 T cells in chronic hepatitis B (CHB), particularly during interferon-alpha (IFN-α) treatment, is not fully understood. This study aims to elucidate the relationship between CXCR5CD8 T cells and sustained serologic response (SR) in patients undergoing 48 weeks of pegylated IFN-α (peg-IFN-α) treatment for CHB.

Influenza A virus (IAV) is a significant public health concern, causing seasonal outbreaks and occasional pandemics. These outbreaks result from changes in the virus's surface proteins which include hemagglutinin and neuraminidase. Influenza A virus has a vast reservoir, including wild birds, pigs, horses, domestic and marine animals.

Mycoplasma pneumoniae caused lower respiratory tract infection in children and can exacerbate these infections through the production of various inflammatory factors, with chemokines playing a key role. However, the pathogenesis of this infection is complicated and thus has not been thoroughly studied. We clarified that cytokine expression levels were analyzed in both peripheral blood and bronchoalveolar lavage fluid (BALF), and in vitro assays were conducted using THP-1 macrophages.

The only current strategy to test efficacy of novel interventions for sustained HIV control without antiretroviral therapy (ART) among people with HIV (PWH) is through an analytical treatment interruption (ATI). Inclusion of 'placebo' controls in ATIs poses ethical, logistical, and economic challenges. To understand viral dynamics and rates of post-treatment control (PTC) after ATI among PWH receiving either placebo or no intervention, we undertook an individual-participant data meta-analysis.

Viral infections persist as a significant cause of morbidity and mortality worldwide. Conventional therapeutic approaches often fall short in fully eliminating viral infections, primarily due to the emergence of drug resistance. Natural killer (NK) cells, one of the important members of the innate immune system, possess potent immunosurveillance and cytotoxic functions, thereby playing a crucial role in the host's defense against viral infections.
