Lipopolysaccharides, from S. enterica (Salmonella enterica) serotype enteritidis, are endotoxins derived from this serotype known for causing enteritis and serve as TLR-4 activators. This S-type LPS triggers the immune system's pathogen-associated molecular patterns (PAMP) and induces the secretion of exosomes. It consists of a typical tripartite structure: the O antigen, core oligosaccharide, and lipid A. These lipopolysaccharides can provoke a systemic inflammatory response, leading to increased plasma levels of TNF-α, IFN-γ, IL-6, IL-10, and nitrates.

Lipopolysaccharides (LPS) are specific endotoxins that serve as a major component of the cell walls in gram-negative bacteria. Composed of Lipid A, a core oligosaccharide, and an O-specific polysaccharide, LPS strongly stimulates the immune system by binding to Toll-like receptor 4 (TLR4) on immune cells, triggering inflammatory responses. In most Salmonella serotypes, the LPS features a complex O-antigen (OAg) structure, with core oligosaccharide OAg units ranging from 16 to over 100 repeats. Mutations in OAg regulatory factors can alter the OAg structure, affecting Salmonella interactions with epithelial cells. Strains with long OAgs show increased translocation and invasion by SPI1-T3SS effector proteins, while strains lacking OAg entirely exhibit increased invasiveness and adhesion. This product is derived from Salmonella enterica serotype minnesota and is utilized for studies on host immune activation and its roles in inflammation and immune modulation.

Lipopolysaccharides, from S. enterica (Salmonella enterica) serotype typhimurium, are endotoxins and TLR4 activators derived from the serotype of this bacterium, classified as S-type LPS. They display a characteristic three-part structure: O antigen, core oligosaccharide, and lipid A. These lipopolysaccharides influence bacterial fate within dendritic cells (DC), determining the uptake, degradation, and activation of immune functions in DC cells.

Lipopolysaccharides from *Salmonella enterica* serotype Abortusequi are endotoxins and TLR-4 activators derived from intestinal S. enterica. They are mutated R-type LPSs that serve as pathogen-associated molecular patterns (PAMP) to activate the immune system and induce cell secretion of exosomes. These lipopolysaccharides consist of a core oligosaccharide and lipid A. *S. enterica* serotype Abortusequi is a key pathogen causing abortion in mares and is associated with neonatal septicemia, multiple abscesses, orchitis, and polyarthritis in equine species. Grouping is primarily based on lipopolysaccharide (O-antigen) and flagellin protein (H-antigen).

Rebaudioside D is a potential sweetener. Rebaudioside D shows similar stability when exposed to simulate stomach and small intestine fluids, with susceptibility to hydrolytic degradation by enteric bacteria collected from the cecum.

Sulfadimethoxine is a antimicrobial agent, treatment of respiratory, urinary tract, enteric, and soft tissue infections

Gastrin-Releasing Peptide, human(TFA) is a regulatory human peptide that elicits gastrin release and regulates gastric acid secretion and enteric motor function. The post-ganglionic fibers of the vagus nerve that innervate the G cells of the stomach release GRP, which stimulates the G cells to release gastrin.

RS 23579-190 is a highly selective 5-HT receptor antagonist in neuropharmacology. Capable of specifically blocking serotonin-mediated downstream excitatory postsynaptic potentials at picomolar concentrations, it is frequently used to dissect serotonergic signaling pathways within the gastrointestinal enteric nervous system and central cognitive networks.

Alosetron hydrochloride (GR 68755) is the hydrochloride salt form of alosetron, a potent and selective 5-HT3 receptor antagonist. Alosetron blocks the actions of serotonin at 5-HT3 sites in the peripheral nervous system, particularly on enteric and nociceptive sensory neurons, thereby affecting the regulation of visceral pain, decreasing gastrointestinal contraction and motility, and decreasing gastrointestinal secretions.
