It is important to highlight that infection with the human immunodeficiency virus (HIV) may trigger chronic inflammation in people living with HIV/AIDS (PLWHA), impacting to the key immune cells such B and T lymphocytes, leading to development of autoantibodies which might be potential to developed autoimmune phenomenon. This study represent the first investigation in Sudan designed to evaluate and determine the prevalence of Antinuclear autoantibody (ANA) among people living with HIV/AIDS by systematically charaterizing ANA staining patterns; distribution, frequency and their correlation with estimated endpoint titers and interplay of age -sex specific ANA patterns in the context of HIV infection post antiretroviral therapy era. Using Serum samples of one hundred and sixteen (116) HIV-infected patients admitted to two major Voluntary Testing and Counseling (VTC), of the HIV clinical centers at the Military Hospital and Bahri Hospital in Khartoum, Sudan, have been assessed for ANA screening. A total of 116 HIV confirmed cases, were screened for ANA autoantibodies using HEp-2 cell indirect immunofluorescent technique. out of 116 85/116 (73.3%) were showed positivity for ANA. the proportion of ANA positivity among the male group was higher than the female group, 49/65 (75.4%) and 36/51 (70.6%), respectively, but there are no significant statistical differences (p = 0.7). Interestingly, a high proportion of positivity for ANA were found in the older subject groups (aged 42-56 years and > 57 years), with rates of 80% for each. Furthermore, our study also showed that the predominant ANA patterns were nuclear fine-speckled (AC-4, 56.5%) followed by cytoplasmic fine granules (AC-20, 24.7%). This study suggests that HIV might induced chronic inflammation and trigger the production of autoantibodies with variable specificities, needing further studies to better understand the role of HIV-driven chronic inflammation in shaping autoimmune serological profiles in these patients.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Metaflammation, a chronic immune response triggered by metabolic dysregulation, poses significant threats to gut-liver homeostasis in aquaculture species. To understand the progression of metaflammation, it is crucial to examine the role of SOCS8 deficiency in socs8 zebrafish, as this species may serve as a disease model for metabolic disorders due to the gradual dysregulation of immunity, metabolism, and the gut microbiota observed in them. This study examines the immune-metabolic crosstalk in grass carp, subjected to soybean meal-induced enteritis, and in socs8 zebrafish under genetic and dietary stress.

Conventional wound dressings primarily focus on biochemical regulation, often neglecting the potential benefits of mechanical cues in tissue regeneration. We report a Janus hydrogel (QPJ hydrogel) that synergistically integrates biochemical modulation with temperature-responsive mechanical contraction for advanced chronic wound management. The hydrogel is constructed from quaternary ammonium chitosan (QCS) and N-isopropylacrylamide (NIPAM), with an outer PNIPAM layer that generates a directional contractile stress >25 kPa at physiological temperature.

Lumbar spinal stenosis (LSS) is one of the most common spinal disorders in elderly people and is often accompanied by neuropathic pain. Although our previous studies have demonstrated that infiltrating macrophage contribute to chronic neuropathic pain in LSS rat model, the molecular mechanisms underlying macrophage activation and infiltration have not been fully elucidated. In this study, we examined the critical role of platelet-derived growth factor receptor (PDGFR) signaling pathway in neuropathic pain associated with macrophage infiltration and activation in LSS rats.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most prevalent urological condition in men under 50, characterized by persistent or recurrent pelvic and perineal pain, and significantly reduced quality of life. Reliable biomarkers for assessment and mechanistic understanding of pain remain limited. This retrospective case-control study consisting of 90 CP/CPPS patients (median age 29.
