Human serum albumin  (Synonyms: HSA)

Human serum albumin (HSA) is the most abundant protein in plasma and is a major determinant of plasma oncotic pressure. Human serum albumin exhibits antioxidant, anticoagulant, anti-inflammatory, anti-platelet aggregation activities as well as colloid osmotic action. Human serum albumin can block the inhibitory effect of GML on human T cells, providing protective function for T cells. Human serum albumin is also associated with cardiovascular diseases and can partially prevent the LPS (HY-D1056) induced oxidative stress, as well as the upregulation of NF-κB, NF-κB, and peroxynitrite (ONOO⁻) in the vascular wall, contributing to the reduction of blood pressure^[1][2][3].

HAS (5 μM, 0-90 minutes) can bind with Glycerol Monolaurate (GML), with a K_d value of 1.4 μM. HSA can prevent the ability of GML to inhibit human T cells and protect the function of T cells^[3].
HSA (0.01, 0.05, 0.1 μM, 0-24 h) alleviates the GML-induced phosphorylation of AKT at threonine 308 and serine 473 residues as well as the formation of LAT, PLC-γ1, and AKT microclusters, and restores the production of IFN-γ, IL-2, IL-10, and TNF-α in GML-treated cells^[3].

Human serum albumin (10 ml/kg; Intravenous injection; Once at 1 hour and once at 5 hours; twice) partially prevents the oxidative stress induced by LPS (HY-D1056) (50 mg/kg) in male Swiss mouse models, as well as the decrease in blood pressure due to upregulation of NF-κB, iNOS, and peroxynitrite (ONOO⁻) in the vascular wall^[4].
Human serum albumin (10 ml/kg; Intravenous injection; Once at 1 hour and once at 5 hours; twice) in a Male Swiss mouse model completely prevented endotoxin-induced reduced vascular response to phenol catecholamines, electromyotonia, and endothelial dysfunction, and reduced inflammatory processes leading to oxidative and nitrite stress and reduced vascular reactivity^[4].
