Article Abstract
A rationally designed oral vaccine should be successfully delivered to the intestinal mucosal immune cells, and induce both humoral and cellular counterparts of immunity along with the mucosal immune response. The aim of this study is to mimic these natural infections and excel the utility of a specific ligand for beta1 integrin (RGD peptide) to target M cells which seems to be the only portal for any particulate matter in GIT. The in vivo studies have shown higher antibody titre for alginate coated chitosan nanoparticles compared to plain chitosan nanoparticles. RGD peptide conjugated alginate coated chitosan nanoparticles proved to be the suitable carrier system for antigen delivery to gut associated lymphoid tissue. Based upon the release kinetics and strong systemic as well as mucosal immune response we can conclude that this cost effective carrier construct can be utilized for oral vaccination.

Vitamin D has been proposed to attenuate chemotherapy-induced gastrointestinal mucositis (GM). In the intestine, local catabolism of active vitamin D [1,25-dihydroxyvitamin D₃] is mediated by the enzyme Cyp24a1. This study assessed whether deletion of Cyp24a1 specifically in intestinal epithelial cells can protect against 5-fluorouracil (5-FU)-induced intestinal injury and microbiome disruption in mice.

The increasing prevalence of respiratory disorders highlights the urgent need for effective mucosal vaccines that elicit targeted immune responses at pathogen entry sites. However, the advancement of mucosal vaccines is limited by challenges in antigen delivery and overcoming mucosal immune tolerance. In this study, we developed a gene delivery platform using chitosan functionalized with lactobionic acid (LA) to enhance targeting of antigen-presenting cells and to form stable DNA polyplexes with high transfection efficiency.

The human microbiome plays a critical role in health and disease. Disruptions in microbiota composition or function have been implicated not only as markers but also as drivers of diverse pathologies, creating opportunities for targeted microbiome interventions. Advancing these therapies requires experimental models that can unravel the complex, bidirectional interactions between human tissue and microbial communities.

Ethnopharmacological Relevance: Shen Ling Bai Zhu San (SLBZS) is a classical Chinese herbal formula and has been used for treating chronic diarrhea (CD) for several centuries. However, there is a lack of robust evidence on how SLBZS regulates immune function to improve CD.
Aim Of The Study: To reveal the spleen-invigorating and antidiarrheal effects of SLBZS in chronic diarrhea mice induced by spleen-deficiency, as well as to explore the underlying mechanism.

Mycoplasma gallisepticum (MG) is one of the main pathogens causing chronic respiratory diseases in chickens, which seriously affects the sustainable and healthy development of the poultry industry and leading to heavy economic losses. Therefore, we developed a safe, efficient, convenient, and low-cost MG oral vaccine. The vaccine is based on a recombinant yeast surface display system to compensate for the shortcomings of existing vaccines.
