The epidermis is the outermost layer of skin, and it contains several different types of cells. These cells include keratinocytes (helps to give the epidermis its strength), melanocytes (produce melanin that gives the skin its pigment/color), Langerhans cells (functions as part of the immune sys...
Where are stratified squamous cells found? What is the function of simple squamous epithelium? What type of cells does the periosteum contain? What does epithelial cells in sputum mean? What kind of cells are found in the basal layer of the skin? What is an example of epithelial tissue? Wh...
There are four different types of melanoma cancer. Three of them begin 'in situ', which means they occupy and spread in the top layer of the skin and can become invasive. The fourth type is invasive from the start. Superficial spreading melanoma is the most common of the melanomas. It...
Epithelial cells are found throughout the body. The majority of epithelial cells, however, are skin cells. These form the protective barrier on the outside of the body designed to keep germs out and our fluids in.Answer and Explanation: ...
To study the endocrine function of the pancreas, the islets of Langerhans are of extreme importance. The islets have 4 kinds of cells where each produces a completely different hormone for secretion into the blood. The Alpha cells produce Glucagon and Beta cells produce insulin. Both these hormon...
Stratum spinosum (spiny layer)- This is the thickest layer and consists of squamous cells (prickle cells) and is located above stratum basale. Here, cells produce keratin, a tough protein that can also be found in nails and hair. Langerhans cells (antigen-presenting cells) can also be found...
In psoriasis, these T-cells attack and kill the skin cells, as if they were external threats. The body boosts the production of dermal cells by almost 10 times, to make up for the loss as if it were trying to heal a wound. Together, these abnormalities lead to inflamed patches that ...
The function of vitamin D as a potent modulator of the innate and adaptive immune system in the eye has been supported by in vivo studies showing that vitamin D is able to inhibit corneal inflammation by suppressing the migration of Langerhans cells into the cornea [109], curbing the excessive...
are involved in many cutaneous inflammatory, infectious, and neoplastic disorders. We extensively reviewed the implication of soluble factors in skin innate immunity. Furthermore, we showed which molecules target these factors, how these molecules work, and how they have been used in dermatological ...
