Involucrin is a highly reactive, soluble, transglutaminase substrate protein present in keratinocytes of epidermis and other stratified squamous epithelia. [7] [8] It first appears in the cell cytosol, but ultimately becomes cross-linked to membrane proteins by transglutaminase thus helping in the formation of an insoluble envelope beneath the plasma membrane functioning as a glutamyl donor ...
Micrograph of keratinocytes, basal cells and melanocytes in the epidermis Keratinocytes (stained green) in the skin of a mouse. Keratinocytes are the primary type of cell found in the epidermis, the outermost layer of the skin. In humans, they constitute 90% of epidermal skin cells. [1]
Microscopy of keratin filaments inside cells. Keratin (/ ˈ k ɛr ə t ɪ n / [1] [2]) is one of a family of structural fibrous proteins also known as scleroproteins.It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates.
Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs blue and red wavelengths of light while reflecting a majority of green. It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b.
A deficiency is associated with ichthyosis lamellaris. [11] Epidermal transglutaminase is the autoantigen, in humans, of dermatitis herpetiformis.. A study on the mutation of keratinocyte transglutaminase (TGK) came to conclude that those affected with ichthyosis lamellaris, present a substantial deficit in keratinocyte transglutaminase activity. [8]
A week after wind-whipped wildfires began their deadly rampage through Southern California, investigators search for clues into what started the devastating blazes. The answers may take months or ...
The homeostasis function is regulated by the calcium gradient in the epidermis. [17] Usually the calcium level is very low in stratum corneum, but high in stratum granulosum. Once the permeability barrier is disrupted an influx of water occurs in the stratum corneum, which in turn increases the calcium levels in the stratum corneum but ...
A knife-wielding teenager is facing felony charges after stabbing another youngster during a heated dispute inside of a Long Island Macy’s, cops said. The argument between two 17-year-old boys ...
