ACE inhibitors are a class of drugs that work by relaxing blood vessels, inhibiting the production of the vasoconstrictor substance Angiotensin II. This results in lower blood pressure, reduced cardiac load, and decreased risk of hypertension.

4-1BB (also known as CD137 or TNFRSF9) was first discovered in 1989 and is a critical co-stimulation receptor on T cells and other immune cells.

The TLR agonists used in vaccine formulations come in various forms, ranging from lipopeptides to single-stranded DNA and RNA.

TLRs are innate immune receptors that are responsible, directly or indirectly, for detecting pathogen-associated molecular patterns (PAMPs) and responding to them through the activation of innate and adaptive immune pathways.

Endothelin receptor are G protein-coupled receptors (GPCRs) of the β-group of rhodopsin receptors that bind to endothelin ligands, which are 21 amino acid long peptides derived from longer prepro-endothelin precursors.

The D2 receptor is a type of dopamine receptor found in the human body. It plays a crucial role in various physiological and neurological processes.

Factor Xa is a key protease of the coagulation pathway whose activity is known to be in part modulated by binding to factor Va and sodium ions.

CDKs or cyclin-dependent kinase,are a group of enzymes that play a crucial role in regulating the cell cycle in the human body.

DHFR, or dihydrofolate reductase, is an indispensable enzyme required for the survival of most prokaryotic and eukaryotic cells as it is involved in the biosynthesis of essential cellular components.

FcRn, or neonatal Fc receptor, is a crucial protein found in the human body that plays a significant role in the immune system and the pharmacokinetics of therapeutic antibodies.

ERK, also known as Extracellular Signal-Regulated Kinase, is a crucial protein kinase that plays a significant role in various cellular processes within the human body.

The D2 receptor is a type of dopamine receptor found in the human body. It plays a crucial role in various physiological and neurological processes.
