Food and Drug Administration approval of the first microbiome therapies represents a true expansion the treatment paradigm for Clostridioides difficile but raises new questions about the future role of fecal microbiota transplantation. The authors outline the advances in microbiome therapeutic development that have addressed fecal microbiota transplantation's (FMT's) inherent limitations of safety and scalability. The authors also suggest that as microbiome therapeutic development continues for other indications, FMT will likely remain a necessary model of human microbiota dynamics for translational research.

The polymorphic microbiome is considered a new hallmark of cancer. Advances in High-Throughput Sequencing have fostered rapid developments in microbiome research. The interaction between cancer cells, immune cells, and microbiota is defined as the immuno-oncology microbiome (IOM) axis.

Tertiary lymphoid structures (TLSs) are de novo ectopic lymphoid aggregates that regulate immunity in chronically inflamed tissues, including tumours. Although TLSs form due to inflammation-triggered activation of the lymphotoxin (LT)-LTβ receptor (LTβR) pathway, the inflammatory signals and cells that induce TLSs remain incompletely identified. Here we show that interleukin-33 (IL-33), the alarmin released by inflamed tissues, induces TLSs.

Snakebite envenoming remains a devastating and neglected tropical disease, claiming over 100,000 lives annually and causing severe complications and long-lasting disabilities for many more. Three-finger toxins (3FTx) are highly toxic components of elapid snake venoms that can cause diverse pathologies, including severe tissue damage and inhibition of nicotinic acetylcholine receptors, resulting in life-threatening neurotoxicity. At present, the only available treatments for snakebites consist of polyclonal antibodies derived from the plasma of immunized animals, which have high cost and limited efficacy against 3FTxs.

Background: Whether improvements in gastrointestinal (GI) symptoms observed with Elexacaftor/Tezacaftor/Ivacaftor (ETI) treatment are sustained in the longer-term requires exploration. This study investigated how GI-symptoms change with longer-term ETI use in pancreatic insufficient adults with cystic fibrosis (awCF).
Methods: Participants completed up to three abdominal symptom questionnaires, employing the validated CFAbd-Score.

Background: Ulcerative colitis (UC), an inflammatory disease characterized by intestinal barrier dysfunction, poses significant challenges because of the toxicity and adverse effects commonly associated with conventional therapies. Safer and more efficacious treatment strategies are needed.
Purpose: The purpose of this study was to treat UC with Folium Artemisiae Argyi exosome-like nanovesicles (FAELNs) and to explore its related mechanism to provide a safer and more effective means for the treatment of ulcerative colitis.
