Human secretin stimulates the secretion of bicarbonate by the pancreas and inhibits the production of gastrin and acid production in the stomach. Human secretin also potentiates the release of digestive enzymes from the pancreas triggered by cholecystokinin.

Substance P is found in the gut and in the brain. It is responsible for a number of excitatory effects on both central and peripheral neurons. Substance P contracts smooth muscle, constricts bronchioles, and increases capillary permeability. When released from afferent nerves, Substance P causes a neurogenic inflammatory response, including mast cell degranulation. It's an NK-1 agonist; a potent vasodilator and hypotensive agent; it induces salivation; it's a putative neurotransmitter in sensory (pain) afferents.

This is a class I (Kb)-restricted peptide epitope of OVA, an octameric peptide from ovalbumin presented by the class I MHC molecule, H-2Kb.

Ghrelin is the first natural appetite stimulant found to be made outside the brain. It is one of a complex array of natural substances that carry messages between the brain and the digestive system. Secreted by specialized cells in the stomach and the upper part of the small intestine, ghrelin acts on the brain. The hormone ghrelin is produced at high levels in the stomach when the organism is hungry and at decreased levels after meals. As such, this hormone plays a critical role in signaling the brain and has become an important focus of obesity research.

ANP(1-28), ratANP (1-28)

Atrial natriuretic peptide (ANP) is synthesized in myoendocrine cells of the heart from which it is released into the circulation. Atrial natriuretic peptide (ANP) exerts natriuretic, diuretic, and vasodilatory effects through stimulation of guanylate cyclase-linked NPR-A receptors. Atrial natriuretic peptide (ANP) plays an important role in blood volume and blood pressure homeostasis.

Potent endogenous opioid protein b-Endorphin is derived from propiomelanocortin, b-Endorphin is a protein found in the brain, anterior pituitary, skin, immune system, and other peripheral sites. β-Endorphin is released in response to painful stimuli and b-Endorphin has potent antinociceptive activity mediated through its action on μ receptors in brain and by μ and κ receptors in the spinal cord.

HA1 fragment 98-106Influenza Hemagglutinin (HA) Peptide

HA Peptide belongs to influenza hemagglutinin (HA) family and is responsible for attaching the virus to cell receptors and for initiating infection.

Glucagon-Like PeptideI; Glucagon-Like Peptide 1; Glucagon-Like Peptide1; GLP-I; GLPI; GLP-1; GLP1; GCG peptide

GLP-1 (7-37) is a truncated, bioactive form of GLP-1 that is the product of proglucagon processing in intestinal endocrine L cells. It is a potent insulinotropic hormone.

The hepatitis B virus (HBV) core protein has been found in the nucleus, the cytoplasm, or both of HBV-infected hepatocytes. nuclear localization of the HBV core protein is negatively regulated by phosphorylation during the cell cycle.

The nonapeptide 149,YFPGQFAFS157 (chemerin-9), corresponding to the C terminus of processed chemerin, retained most of the activity of the full-size protein, with regard to agonism toward the chemerinR.the natural ligand of ChemR23 (chemerinR).
