Melanophores (or melanocytes in humans) contain melanin and are the most common type of chromatophores, responsible for the black, brown, and brownish red coloration of vertebrates. Melanophores contain thousands of melanosomes that vary in size, shape, and composition depending on the type of melanin they contain. Once mature and in place, melanocytes produce melanin, the pigment responsible for skin colour, which is exported to the surrounding keratinocytes (each melanocyte is connected to roughly 40 keratinocytes) in grain-like structures known as melanosomes. So, what’s the major function of melanin, you ask? Melanocytes reside in the basal level of the epidermis at the base of hair follicles and possess many long dendrites that allow intercellular transport of pigment containing melanosomes from the cell body, the site of synthesis, to surrounding keratinocytes (for review see Jackson 1994). Melanophores (or melanocytes in humans) contain melanin and are the most common type of chromatophores, responsible for the black, brown, and brownish red coloration of vertebrates.

Melanosomes and melanocytes

In the skin, melanosomes are transferred from melanocytes to neighboring keratinocytes in order to form perinuclear melanin caps 2016-05-17 To determine the role of autophagy as a melanosome degradation machinery, we administered several autophagy inducers in human keratinocytes and melanocytes.

Melanosomes and melanocytes

Melanosomes, the subcellular site of melanin synthesis and deposition, may be related to the endolysosomal lineage of organelles. To determine if melanosomes contain lysosomal hydrolases, we examined the subcellular distribution of five of these enzymes in melanocytes cultured from C57BL/6J mice. 2018-01-22 · The interaction between keratinocytes and melanocytes is responsible for the synthesis, transfer, transport, and the deposition of melanosomes in the skin. This complete process is known as melanin production.

In summary, structural and enzymatic proteins of the melanosome are processed through the ER and Golgi and sorted into coated vesicles at the TGN. human melanocytes where it partially colocalized with both Tfn on REs and HMB45 on melanosomes (Figure 2). We thus conclude that Rab17 is a resident of both REs and melanosome membranes in melanocytic cells. In con-trast, the quintessential RE Rab, Rab11a, is found on REs but is not evident on HMB45-labeled melanosomes (Figure S1A). 2020-06-12 2014-03-24 2012-02-09 melanosomes interactions with actin filaments at the peripheral site of melanocytes (Wu et al, 1998).
