Increased levels of lactate, an end-product of glycolysis, have been proposed as a potential surrogate marker for metabolic changes during neuronal excitation. These changes in lactate levels can result in decreased brain pH, which has been implicate

Whole picture of human stratum corneum ceramides, including the chain-length diversity of long-chain bases

Autor: Madoka Suzuki, Yusuke Ohno, Akio Kihara

Publikováno v: Journal of Lipid Research, Vol 63, Iss 7, Pp 100235- (2022)

Ceramides are essential lipids for skin permeability barrier function, and a wide variety of ceramide species exist in the stratum corneum (SC). Although ceramides with long-chain bases (LCBs) of various lengths have been identified in the human SC,

Publikováno v: Journal of Lipid Research, Vol 61, Iss 6, Pp 884-895 (2020)

Ceramides are the predominant lipids in the stratum corneum (SC) and are crucial components for normal skin barrier function. Although the composition of various ceramide classes in the human SC has been reported, that in mice is still unknown, despi

Lipid polarity gradient formed by ω-hydroxy lipids in tear film prevents dry eye disease

Publikováno v: eLife, Vol 9 (2020)

Meibum lipids form a lipid layer on the outermost side of the tear film and function to prevent water evaporation and reduce surface tension. (O-Acyl)-ω-hydroxy fatty acids (OAHFAs), a subclass of these lipids, are thought to be involved in connecti
