Article Abstract

Numerous studies establish a significant correlation between autoimmune disorders (AIDs) and prostate cancer (PCa). Our Mendelian randomization (MR) analysis investigates the potential connection between rheumatoid arthritis (RA) and PCa, aiming to confirm causal links between systemic lupus erythematosus (SLE), hyperthyroidism, and PCa. Summary statistics from genome-wide association studies provided data on PCa and three AIDs. MR analysis, using IVW as the main approach, assessed causal relationships, validated by sensitivity analysis. IVW revealed a correlation between genetically anticipated RA and PCa, notably in Europeans (OR = 1.03; 95% CI 1.01-1.04, p = 2*10-5). Evidence supported a lower PCa risk in individuals with SLE (OR = 0.94; 95% CI 0.91-0.97, p = 2*10-4) and hyperthyroidism (OR = 0.02; 95% CI 0.001-0.2, p = 2*10-3). Weighted mode and median confirmed these findings. No pleiotropic effects were observed, and MR heterogeneity tests indicated dataset homogeneity. Our study establishes a causal link between RA, SLE, hyperthyroidism, and PCa.

Role of Splenocytes on T Cells and Its Cytokine Network in Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is a chronic autoimmune condition that impacts the immune system, especially through changes in the splenic immune cell system. This review provides an overview of the role of splenocytes in T cell signaling and their immune response in RA patients. The spleen acts as a critical site for the activation and differentiation of splenic immune cells like T cells, B cells, macrophages, dendritic cells, and NK cells.

IL-2 agonists significantly modulate T cell regulation, impacting activation, proliferation, differentiation, and immune homeostasis. Interleukin-2 (IL-2) is crucial for T cell growth and function, binding to the IL-2 receptor to trigger signaling pathways that balance immune responses. IL-2 promotes the expansion of effector T cells and enhances regulatory T cells (Tregs), preventing autoimmune responses.

Multiple sclerosis (MS) is a chronic neurological disorder characterized by demyelination of the central nervous system (CNS), leading to a broad spectrum of physical and cognitive impairments. Myeloid cells within the CNS, including microglia and border-associated macrophages, play a central role in the neuroinflammatory processes associated with MS. Activation of these cells contributes to the local inflammatory response and promotes the recruitment of additional immune cells into the CNS.

The short lifespan of polymorphonuclear neutrophils (PMNs) in vitro poses challenges, as their limited viability restricts functional assays and experimental manipulations. The HL-60 cell line serves as a valuable model for neutrophil-like differentiation, yet the functional relevance of ATRA- and DMSO-induced differentiation remains incompletely understood. In the present study, we aimed to characterize the differentiation potential of all-trans retinoic acid (ATRA) and dimethyl sulfoxide (DMSO) on HL-60 cells and compare their functionality with primary PMNs.

Background: Few data are available on the impact of primary sclerosing cholangitis (PSC) on inflammatory bowel disease (IBD).

Objective: We conducted a retrospective study using TriNetX to compare the outcomes of patients with IBD and those with concomitant IBD and PSC.

Methods: All patients with a confirmed diagnosis of Crohn's disease (CD), ulcerative colitis (UC), or indeterminate colitis with or without PSC were eligible.
