Melanocyte Essays

Vitiligo is a skin condition that results in the loss of pigment. Melanocytes, the melanin or pigment producing cells within the body, are destroyed; therefore, preventing the body from making pigment for both the skin and the hair. As a result, skin develops white patches throughout and hair may turn white or gray at an early age. The skin is an integral part of the human body. It is made up of two layers, the epidermis and the dermis. In addition, there are specialized cells within the integumentary

suggestion, it is important to understand what an auto immune disease is. An auto immune disorders occur when the cells in the body mistakes parts of itself as a foreign invader, and attacks or kills itself. In this case, scientist suggest that the melanocytes cells attack and kill themselves off. Another type of vitiligo, called segmental vitiligo, is suggested to occur when the there is some sort of disarray in the nervous system, though scientist and researcher cannot exactly pin point what that disconnect

Most of you must have an experience in feeling sweating, feeling burn, and skin turning to red, as red as skin of shrimp when it was being boiling when being exposed to direct sunlight. All of you must feel not comfortable with those conditions, right? So, today I am going to talk about the sunburn problem and the solution to this problem. I want to tell you about this as I am obsessed with health, skin care and skin beauty and I have gained much information from many sources that I have read. So

Vitiligo is a genetic phenomenon that relates to gene structure because of an abnormality of the vitiligo melanocytes. These melanocytes develops from a defect in the immune system. Because of this defect, skin depigmentation is caused. In Vitiligo, the melanocytes components target the immune system. Because of this destruction of the immune system, vitiligo affects the coloration of body features (Ben, 2014). These body features include the eyes, the skin, and the hair. But, given this disease’s

negative ways, possibly leading to Melanoma skin cancer. Melanoma is the most serious type of skin cancer that arises from the melanocytes. The cells that play an important role in the skin are the keratinocyte and the melanocyte. The keratinocyte is the formation of the keratin layer that protects the skin and the underlying tissues from the environmental damages. Melanocytes are the cells that are involved and responsible for the person's skin and hair color which produce a skin pigment called melanin

skin. Having any melanin in keratinocytes helps protect both my epidermis and the dermis layers of skin. Where my skin is naturally darker this happens in my stratum granulosum layer. By being in the sun my skin was exposed to UV radiation. The melanocytes react to the UV radiation by increasing their activity and increasing the amount of melanin in the keratinocytes. Too much UV radiation can damage the core of my cells -the DNA, however just a bit has helped as my epidermis created calcium ions

They found that this chemical builds up on the hair shaft, just above the bulb of the hair follicle and sits there until broken down. After melanin is produced, it is ordinarily excreted out the melanocyte into the medulla of the hair follicle. Before entering the medulla, the melanin is bleached by the hydrogen peroxide solution present in the follicle. All follicles contain small quantities of hydrogen peroxide so when the bleaching occurs it is

cancer is a cancer that starts in a specific skin cell. The main type of skin cells that lead to cancer in your body are Squamous cells, Basal cells and, Melanocytes. Melanoma starts from the Melanocytes. Melanocytes is a skin cell that makes the skin darken when you are in the sun for a long period of time by the help of melanin. Melanocytes produces melanin, melanin leads to a long lasting pigmentation on the skin. You can get Melanoma anywhere in the body such as eyes, mouth, chest, back, hands

Vitiligo or alternatively known as Primary acromia1 or Idiopathic leukoderma1, is a benign skin disease2, it is the most common type of leukoderma3(p.974) which is described as “localised complete loss of skin”2. Vitiligo is characterised by hypopigmentation. Hypopigmentation occurs when pigment in the skin is lost, it appears in irregular shapes and sizes on different parts of the body, including mucous membranes and the retina. Vitiligo occurs in both sexes and among all races, it is not contagious

SKIN LAYERS Skin is called as integumentary system of three layers as following: 1. Epidermis 2. Dermis 3. Hypodermis 1.2.1. Epidermis It is the upper layer which provides waterproof barrier and creates color tone because of the presence of melanocytes, which produce melanin pigment. 95% of epidermis is consist of Keratinocytes, which are characterized by cytokeratin

(color) which determines our tone, these cells are called Melanocytes. Vitiligo destroys melanocytes, therefore, causing the milk-white skin tone. Vitiligo can also affect the mucous membrane, such as the tissues inside the mouth, nose and eye. The cause of Vitiligo is not known. It is an autoimmune disease, in which your immune system will mistakenly attack some parts of your body. In this case, the immune system destroys the melanocytes in the skin causing

Vitiligo is a disease that causes the loss of skin color in blotches on the body. It is a condition where the extent and rate of the color loss is unpredictable and can depend greatly on the person with the condition. Vitiligo can affect any part of the skin on the body, and there are no limits on where or how much of the disease can spread (Mayo Clinic). Vitiligo is not frequent in the global population. Studies show that vitiligo has a frequency of 0.1-2.0% in the various populations (Spritz 2003)

where it is mainly comprised of adipose tissue and is therefore not examined as part of the skin. In the epidermis of the skin, there are specialized cells located in several distinct layers. The main epidermal cells are the keratinocytes and melanocytes.

better control of neoplastic spread to regional lymph nodes for lesions that are thicker than 0.76 mm. Malignant melanoma is a neoplasm arising from melanocytes. Melanocytes are melanin producing cells that are located in the bottom layer of the epidermis, which is called the stratum basale and they are also present in hair follicles. Melanocytes are a type of specialized skin

Hello fellow steemians Thank you so much for stopping by.Here is something you probably want to check out. Today we will be discussing on a very interesting and most indistinct entity of human life, The Melanin.I hope you will love to read it. Bible says "Elohim formed a man from the Dust of the ground and breathed into his nostrils the breath of life and the man became a living being." As seeds growing from dirt turns into plants, and plants utilize chlorophyll to absorb radiations for survival

Society hears the word cancer and automatically associates it with something bad. People hear about it all the time, but do they really know what it is? What is Cancer? Cancer is a disease made up of a malignant growth or tumor, because the uncontrolled division of abnormal cells. Now in English, cancer is an abnormal growth of some sort. The growth has to be malignant, because malignant means cancerous. People have wondered if cancer can be prevented, can it? Yes, with the appropriate education

“The true white horse does not exist”, almost everyone in the Equine world has heard this at one time or another. The reason that a true white horse does not exist, is because of the Overo Lethal White Syndrome or OLWS for short. Although it can be called many names, this is the most common. This syndrome affects horses of the overo gene pool. An overo is a type of white coat pattern that occurs in several breads of horses. The white coat patches can be associated with any type of coat pattern

MELANOTAN II PRODUCT DESCRIPTION Melanotan II is a lab synthesized peptide hormone that imitates melanocyte-stimulating hormone (a hormone that naturally occurs in the human body). Alpha-MSH (also referred to as α-MSH or alpha-melanocyte-stimulating hormone (MSHs) stimulates the melanogenesis; the process by which the skin and hair darkening pigments are produced in mammals. In vitro administration of Melanotan II has been observed to have excellent portent melanotropic action. The structural name

TITLE: BLADDER MELANOSIS: A RARE CASE REPORT INTRODUCTION Melanosis is defined as an abnormal deposit of melanin pigment in the tissues and was first described in 1986 [1]. It can be seen in any organ, but more often is described and characterized in oral mucosa and skin. Bladder melanosis (or melanosis vesicae) is an extremely rare condition and, so far, less than 20 cases have been reported in the literature, making its diagnosis difficult. Here, we describe a new case, show our histopathological

Tanning is the darkening of the skin through indoor tanning beds or outdoor tanning. It can help against many diseases. These diseases include osteoporosis, rickets, tuberculosis and having enough vitamins in the body. Dr. Edwin E. Slosson, in the article “Tanning” makes a statement, “it seems that ultra-violet and violet rays may be positively beneficial.” At the time of his statement it was the beginning of when tanning became popular. What he was not aware of was all the long term effects of tanning
