General description

A potent, selective, competitive, and high affinity inhibitor of arginase. Shown to inhibit arginase from rat liver (IC50 = 2 µM) and mouse macrophages (IC50 = 50 µM). Shown to specifically interact with the manganese-cluster of the enzyme active site. Does not function as a substrate or as an inhibitor for NOS. Hence, nor-NOHA may be a useful tool to study the interplays between arginase and NOS.

Decompensated cirrhosis patients are more prone to bacterial infections. Myeloid-derived suppressor cells (MDSCs) expand in sepsis patients and disrupt immune cell functions. Granulocyte-macrophage colony-stimulating factor (GM-CSF) therapy helps in restoring immune cell functions and resolving infections. Its role in MDSC

The immunological mechanisms underlying the clinical presentation of SARS-CoV-2 infection and those influencing the disease outcome remain to be defined. Myeloid-derived suppressor cells (MDSC) have been described to be highly increased during COVID-19, however, their role remains elusive. We performed

IL1β is a central mediator of inflammation. Secretion of IL1β typically requires proteolytic maturation by the inflammasome and formation of membrane pores by gasdermin D (GSDMD). Emerging evidence suggests an important role for IL1β in promoting cancer progression in patients
