The re-emergence and transmission of Monkeypox virus in Nigeria: the role of one health.

The Monkeypox virus, commonly abbreviated as mpox, is a viral zoonosis that is experiencing a resurgence in prevalence. It is endemic to regions of West and Central Africa that are characterized by dense forested areas. Various measures pertaining to animals, humans, and the environment have been recognized as potential factors and catalysts for the spread of the disease throughout the impacted regions of Africa.

CES1 Releases Oxylipins from Oxidized Triacylglycerol (oxTAG) and Regulates Macrophage oxTAG/TAG Accumulation and PGE/IL-1β Production.

Triacylglycerols (TAGs) are storage forms of fat, primarily found in cytoplasmic lipid droplets in cells. TAGs are broken down to their component free fatty acids by lipolytic enzymes when fuel reserves are required. However, polyunsaturated fatty acid (PUFA)-containing TAGs are susceptible to nonenzymatic oxidation reactions, leading to the formation of oxylipins that are esterified to the glycerol backbone (termed oxTAGs).

Carboxylesterase 1d Inactivation Augments Lung Inflammation in Mice.

Carboxylesterases are members of the serine hydrolase superfamily and metabolize drugs, pesticides, and lipids. Previous research showed that inhibition of carboxylesterase 1 (CES1) in human macrophages altered the immunomodulatory effects of lipid mediators called prostaglandin glyceryl esters, which are produced by cyclooxygenase-catalyzed oxygenation of the endocannabinoid 2-arachidonoylglycerol (2-AG). Ces1d - the mouse ortholog of human CES1 - is the most abundant Ces isoform in murine lung tissues and alveolar macrophages and a major target of organophosphate poisons.
