This chapter discusses the background knowledge about the enteric nervous system (ENS) as well as the role of ENS in secretory states of the small intestine. The chapter describes the anatomy and physiology of the ENS. A description of the experimental evidence for the involvement of ENS in secretory states of the gut, primarily in cholera toxin-induced secretion that is the most thoroughly investigated secretory state, is presented in the chapter. The chapter focuses on the involvement of ENS in rotavirus (RV) diarrhea. The involvement of the ENS in diarrhea pathophysiology opens up new potential sites of action for drugs in the treatment of intestinal secretory states. The chapter concludes with a discussion of the sites of action for the pharmacological treatment of diarrhea.

As an important industrial enzyme, chymosin has been widely used in cheese manufacturing. Fermentation with Kluyveromyces lactis has allowed recombinant chymosin production to fit the growing global demand for cheese consumption; yet improvements can be made to allow for stable and larger-scale production. In this work, various chymosin producing (CP) strains were constructed via targeted chromosomal integration of various copies of a prochymosin expression cassette (PEC) using a CRISPR-Cas9 platform optimized for K.

Background: Ionizing radiation (IR) is a well-known inducer of cellular senescence and the senescence-associated secretory phenotype (SASP). SASP factors play dual roles in cancer, either promoting or inhibiting its development. This study investigates IR-induced SASP factors specifically secreted by renal cortical epithelial (RCE) cells and their role in promoting renal cell carcinoma (RCC) progression.

Nanobodies have gained attention as potential therapeutic and diagnostic agents for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) due to their ability to bind and neutralize the virus. However, rapid, scalable, and robust production of nanobodies for SARS-CoV-2 remains a crucial challenge. In this study, we developed a visual and high-efficiency biomanufacturing method for nanobodies with by fusing the super-folder green fluorescent protein (sfGFP) to the N-terminus or C-terminus of the nanobody.

Deployment-related constrictive bronchiolitis (DRCB) has emerged as a health concern in military personnel returning from Southwest Asia. Exposure to smoke from a fire at the Al-Mishraq sulfur enrichment facility and/or burn pits was reported by a subset of Veterans diagnosed with this disorder. DRCB is characterized by thickening and fibrosis of small airways (SA) in the lung, but whether these are related to toxin inhalation remains uncertain.

Background: Endocytosis of enamel matrix proteins (EMPs) by ameloblasts is a key process in the mineralization of enamel during the maturation stage of amelogenesis. However, the relevant receptor mediating endocytosis of EMPs is still unclear. The aim of this study was to explore potential endocytic receptors involved in this process.
