Self-proliferation of the pathological form of α-synuclein was identified as one of the main pathophysiological presentations of Parkinson's disease (PD) a decade ago. Although inflammation has also been suggested to contribute to PD pathogenesis, it is unclear whether this is associated with the pathological spread of α-synuclein aggregation. Herein, we evaluated two main neuroinflammatory processes in the striatum-microgliosis and astrogliosis-after the injection of preformed fibrils of α-synuclein into the mouse striatum. Thus, our study demonstrated that microgliosis accompanied α-synuclein propagation, while astrogliosis did not. Therefore, we report a preferential association between microglia and the process of α-synuclein proliferation.

Large-scale gene-environment interaction (GxE) discovery efforts often involve analytical compromises for the sake of data harmonization and statistical power. Refinement of exposures, covariates, outcomes, and population subsets may be helpful to establish often-elusive replication and evaluate potential clinical utility. Here, we used additional datasets, an expanded set of statistical models, and interrogation of lipoprotein metabolism via nuclear magnetic resonance (NMR)-based lipoprotein subfractions to refine a previously discovered GxE modifying the relationship between physical activity (PA) and HDL-cholesterol (HDL-C).

Objectives: We assessed HIV-1 drug resistance profiles among people living with HIV (PLWH) with detectable viral load (VL) and on dolutegravir-based antiretroviral therapy (ART) in Botswana.

Methods: The study utilised available 100 residual HIV-1 VL samples from unique PLWH in Francistown who had viraemia at-least 6 months after initiating ART in Botswana's national ART program from November 2023 to January 2024. Viraemia was categorized as low-level viraemia (LLV) (VL: 200-999 copies/mL) or virologic failure (VF) (VL ≥1000 copies/mL).

Objective: Margin distance is a significant prognosticator in oral cavity cancer but its role in HPV-related oropharyngeal squamous cell carcinoma [HPV(+)OPSCC] remains unclear. Here, we investigate the impact of margin distance on locoregional recurrence in HPV(+)OPSCC.

Study Design: This is a retrospective cohort study of surgically treated HPV(+)OPSCC patients.

Background: Ischemic stroke is a prevalent and life-threatening cerebrovascular disease that is challenging to treat and associated with a poor prognosis. Astragaloside IV (AS-IV), a primary bioactive component of Astragali radix, has demonstrated neuroprotective benefits in previous studies. This study aimed to explore the mechanisms through which AS-IV may treat cerebral ischemia-reperfusion injury (CIRI).

Cancer-associated fibroblasts (CAFs) are intrinsic components of the tumor microenvironment that promote cancer progression and metastasis. Through an unbiased integrated analysis of gastric tumor grade and stage, we identified a subset of proangiogenic CAFs characterized by high podoplanin (PDPN) expression, which are significantly enriched in metastatic lesions and secrete chemokine (CC-motif) ligand 2 (CCL2). Mechanistically, PDPN(+) CAFs enhance angiogenesis by activating the AKT/NF-κB signaling pathway.
