Background: COVID-19 is still a significant health concern worldwide. B cell responses to COVID-19 have been extensively studied in acute severe disease, but less so during extended follow-up or mild disease. Persisting immunological changes together with herpesvirus reactivations during acute COVID-19 have been suggested as contributing factors for post-acute sequelae of COVID-19 (PASC).

Background And Aims: Biliary atresia (BA) is a severe neonatal cholangiopathy characterized by progressive inflammation and fibrosis. We aimed to systematically investigate BA pathology using integrated multi-omics.
Methods: Multi-omics integration of BA and control livers revealed sphingolipid dysregulation.

Research Question: What is the composition of bacterial communities at various genital sites and are there potential interactions between partners' microbiota?
Design: This observational study involved metagenomic analyses of samples collected from male and female partners of couples undergoing fertility treatment. Samples included vaginal and penile swabs, as well as follicular fluid and semen, which were analysed using next-generation sequencing.
Results: The bacterial community profiles of different genital tract niches were distinct, niche-specific compositions, with female samples predominantly featuring Lactobacillus species and male samples displaying greater microbial diversity, including genital-specific and skin-associated taxa.

Adaptation of intestinal helminths to vertebrates involved the evolution of strategies to attenuate host tissue damage to support parasite reproduction and dissemination of offspring to the environment. Helminths initiate the IL-25-mediated tuft cell-type 2 innate lymphoid cell (ILC2) circuit that enhances barrier protection of the host, although viable parasites can target and limit this pathway. We used IL-25 alone to create small intestinal adaptation, marked by anatomic and immunologic changes that persisted months after induction.

Moraxella catarrhalis is a Gram-negative diplococcus bacterium and a common respiratory pathogen, implicated in 15-20% of otitis media (OM) cases in children and chronic obstructive pulmonary disease (COPD) in adults. The rise of drug-resistant Moraxella catarrhalis has highlighted the urgent need for the potent vaccine strategies to reduce its clinical burden. Despite a mortality rate of 13%, there is no FDA-approved vaccine for this pathogen.
