stercoralis is more complicated than those of most ob- ligatory parasitic nematodes. Parasitic females (P Female) live in the intestine of the host and reproduce by mitotic parthenogenesis. They lay sexually differentiated eggs; these eggs hatch in the intestine, and post-parasitic first- stage ...
Notably, the local topology of this landscape around a specific taxonomic composition (e.g., point 1) determines whether minor changes in that composition (represented as small movements on this plane; black arrows) will induce small (point 1) or large (point 2) functional shifts. c Depending...
Pepsin:Pepsin is secreted by the stomach to break down proteins intopeptides, or smaller groupings of amino acids. Those amino acids are then either absorbed or broken down further in the small intestine. Trypsin:Trypsinforms when an enzyme secreted by the pancreas is activated by an enzyme in...
Gut microbiota and the intestinal barrier The intestine primarily serves two key functions: the absorption of nutrients and the regulation of the transport of potentially harmful antigens and microorganisms. Functionally, intestinal microbiota plays a pivotal role in modulating intestinal barrier permeability...
differentiate into Teff cells that secrete essential cytokines (including granzyme B, TNFα, and IFNγ) to effectively combat invading pathogens. Following pathogen clearance, most effector cells undergo apoptosis in the contraction phase, while a small population survives and persists as memory T ...
Thyroid hormones are crucial regulators of metamorphosis and development in bilaterians, particularly in chordate deuterostomes. Recent evidence suggests a role for thyroid hormone signaling, principally via 3,5,3′,5′-Tetraiodo-L-thyronine (T4), in the
already exist, lengthen the small intestine’s villi but do not deepen the crypts [117]. Further investigation is required to ascertain whether Am modulates the eCB system through other chemicals or pathways. Fig. 5 Cross-feeding other microbiota...

of immune function-related pathways may be the result of host immune function development or suggest other antigens in the intestine during early life. Further studies focusing on the other antigens and host immune function in the colon mucosa are required to better understand intestinal immune ...
Fucoidan was detected in the small intestine and liver of rats in the oral administration of the drug, indicating that fucoidan could be absorbed by the intestine (Nagamine, Nakazato, Tomioka, Iha, & Nakajima, 2014). Fucoidan can not only stimulate the proliferation of macrophages, but also ...
