Lymphotoxin β receptor (LTβR/TNFRSF3) signaling plays a crucial role in immune defense. Notably, LTβR-deficient (LTβR) mice exhibit severe defects in innate and adaptive immunity against various pathogens and succumb to infection. Here, we investigated the bone marrow (BM) and peritoneal cavity (PerC) compartments of LTβR mice during infection, demonstrating perturbed B-cell and T-cell subpopulations in the absence of LTβR signaling.

Host-pathogen interactions involve two critical strategies: resistance, whereby hosts clear invading microbes, and tolerance, whereby hosts carry high pathogen burden asymptomatically. Here, we investigate mechanisms by which Salmonella-superspreader (SSP) hosts maintain an asymptomatic state during chronic infection. We found that regulatory T cells (Tregs) are essential for this disease-tolerant state, limiting intestinal immunopathology and enabling SSP hosts to thrive, while facilitating Salmonella transmission.

Background: Tachycardia-induced cardiomyopathy (TICM) is typically reversible with rhythm control, but individual susceptibility remains poorly understood and may reflect genetic predisposition.
Case Summary: A 66-year-old woman with paroxysmal atrial fibrillation (AF) presented with new-onset heart failure. Genetic testing identified a likely pathogenic heterozygous ABCC9 gene variant (c.

Despite undisputed success of orthopaedic procedures, surgical site infections (SSI) such as periprosthetic joint infection (PJI) continues to compromise the outcome and result in major clinical and economic burden. The overall rate of infection is expected to rise in the future resulting in significant associated mortality and morbidity. Traditional concepts have largely attributed the source of PJI to exogenous pathogens.

Purpose: Emerging evidence suggests that an abnormal endometrial microbiota may be a potential factor contributing to recurrent pregnancy loss (RPL). This study aimed to characterize the endometrial microbiota in patients with RPL and to explore its association with miscarriage.
Patients And Methods: Based on specific inclusion and exclusion criteria, EndoMetrial Microbiome Assay (EMMA) data from women attending clinics were collected and categorized into RPL and control groups according to their miscarriage history.
