Melanoepithelial cell

A melanoepithelial cell is a type of cell that contains the pigment melanin and is involved in the formation of the iris of the eye.

Melanoepithelial cells are located in the posterior layer of the iris, adjacent to the choroid of the eye. They produce the pigment melanin, which gives the iris its characteristic color and protects the eye from excess ultraviolet radiation.

In addition, melanoepitheliocytes participate in the regulation of intraocular pressure by absorbing excess intraocular fluid from the posterior chamber of the eye. They also play a role in the immunological reactions of the eye.

Thus, melanoepitheliocytes perform important functions in pigmentation, regulation of intraocular pressure and immune protection of the eye. Disturbances in their work can lead to the development of diseases of the iris and other structures of the eye.

***Melanoepitheliocytes*** are skin cells responsible for the production of melanin. Melanin is a pigment that determines the color of human skin and hair. Melaninocytes arise from a variety of cell lineages, including keratinocytes, skin stem cells, and cells of endodermal origin. They play a key role in protecting against ultraviolet radiation and supporting the proper functioning of the skin's pigment apparatus by protecting against UV radiation.

As a rule, our melanoepithelial cells synthesize melanin under the influence of the melanostimulating hormone, melanotropin. The formation and regulation of melanin production in melanocytes is influenced by various factors, such as hormones, biomolecules, microenvironmental cells, macrophages, inflammation, stress and radiation exposure. Basic information about melanins is collected in the form of descriptions of their biological functions from the literature.

It is important to note that people with dark skin have more melanocytes-melanocytes than people with light skin. This is due to an evolutionary mechanism that allows people with light or dark skin tones to adapt to their environment. This explains the skin protection benefit in people with dark skin as a result of increased melanin production over harmful ultraviolet radiation.

Thus, melanin and melanocytes play an important role in the health of our skin. Their production is regulated by hormones, microenvironmental cells and other factors that determine our skin color and protection from harmful ultraviolet radiation. Our skin is a complex organ organism, and understanding the production and regulation of melanin can help us better protect ourselves from sun exposure and other factors that affect our skin.
