Summary: There are significant differences in the prenatal and postnatal development of mucosal enteric glial cells (mEGC) between mice and humans, with mEGCs absent at birth in mice but already present in human fetal gut. Additionally, xenograft experiments show that human mEGCs are more persistent in immuno-compromised mouse hosts compared to murine mEGCs. Single cell RNAseq also indicates disparities in developmental dynamics and gene expression patterns between human and mouse mEGCs.

Summary: The human gastrointestinal tract contains a large number of microorganisms that are involved in various physiological functions. Imbalance in the gut microbiota is closely related to the pathogenesis of several human diseases. Innate lymphoid cells (ILCs), including NK cells, ILC1s, ILC2s, ILC3s, and LTi cells, are a type of immune cells enriched in mucosal tissues and have gained extensive attention. The gut microbiota and its metabolites play important roles in intestinal mucosal diseases such as inflammatory bowel disease (IBD), allergic disease, and cancer. Therefore, studying the interaction between ILCs and the gut microbiota has great clinical significance in identifying potential pharmacotherapy targets for related diseases.

Summary: Mother-to-child transmission of HIV-1 through breastfeeding poses challenges for initiating early antiretroviral therapy (ART). A study using infant rhesus macaques infected with SHIV identified sites of viral persistence under ART, with the gastrointestinal tract being an active site of virus transcription. Naive CD4(+) T cells were found to harbor intact provirus and contribute significantly to the viral reservoir, providing insight into potential targets for cure strategies in pediatric populations.

Summary: The mammalian gut is heavily populated by microbial species, which are constantly in contact with the host. Hosts have developed various mechanisms to distinguish and respond to different bacteria. Unconventional immune cells, such as innate lymphoid cells (ILCs) and unconventional T cells, play essential roles in maintaining gut homeostasis and bridging innate and adaptive immunity in the mucosal barrier. This study highlights the importance of microbiota in regulating the function of ILC subsets and unconventional T cells, and emphasizes the potential of understanding these interactions for enhancing gut health and treating immune-mediated diseases.

Summary: This study investigated the prognostic impact of GV and TV infections on CIN1/L-SIL in HIV-positive women, finding that GV infection is a risk factor for persistence of CIN1/L-SIL while TV infection is a risk factor for progression. Women with these infections may require closer and more careful follow-up of CIN1/L-SIL.

Summary: The involvement of enteric neurons in food allergies has been shown to exacerbate the pathology by interacting with mucosal mast cells, suggesting a potential pathological role of IgE-antigen-activated myenteric neurons in food allergies.

Summary: The diversity and location of microorganisms in the gastrointestinal tract can directly affect viral disease pathogenesis. Infections such as HIV, SIV, and SARS-CoV-2 can cause gastrointestinal pathology, and therapeutic interventions targeting the gastrointestinal tract may improve patient outcomes.

Summary: Exposure of cervical biopsies to complement-opsonized HIV increased the rate of infection, with enhanced expression of genes and proteins associated with viral replication. The findings suggest that HIV opsonization alters signaling pathways in cervical mucosa to promote viral establishment and infection, laying a foundation for further studies on early HIV-induced events in pathogenesis.

Summary: WR-PTXF is a novel pentraxin fusion protein cloned from Carassius cuvieri x Carassius auratus red var. It plays a protective role against bacterial infection by enhancing the uptake of the bound bacteria by host phagocytes.

Summary: By studying infant rhesus macaques and their intestinal samples, it was found that growth faltering is associated with a heightened systemic and mucosal pro-inflammatory state, and a shift in the functional and taxonomic composition of gut microbial communities. These studies provide valuable insights into the outcomes of diarrheal diseases and growth faltering.

Summary: Both innate and adaptive lymphocytes play critical roles in mucosal defense. SCID patients receiving HSCT may have impaired lymphocyte regeneration. SCID patients with IL2RG/GC or JAK3 genetic defects exhibit defects in mucosal immunity and IgA production, leading to microbial dysbiosis. IVIG replacement therapy can partially restore these immune defects.

Summary: After weaning, piglets often experience gut inflammation and reduced performance. The plant-based diet, lack of sow milk, and changes in gut microbiome and metabolite composition may contribute to these symptoms. However, the immediate response of the gut mucosa to these changes is not well understood.

Summary: Selection of a pre-clinical non-human primate (NHP) model is crucial for evaluating therapeutic vaccine and treatment strategies for HIV. Differences in viral control during combination antiretroviral therapy (cART) and gut dysregulation were observed in NHP AIDS models, suggesting that the choice of model may impact the evaluation of candidate therapeutic interventions for HIV treatment and cure strategies. Specifically, SHIV infection resulted in lower acute viremia and less disruption to gut CD4 T-cell homeostasis compared to highly pathogenic SIV Delta B670 infection.
