Mannan-binding lectin the body. It is produced in the liver as a response to infection, and is part of many other factors termed acute phase proteins. Expression and function in other organs were also suggested. The three structural polymorphisms of exon 1 have been reported to cause susceptibility to various common infections, including meningococcal disease. However, evidence has been presented that suggests no harmful effect of these variants with regard to mengingococcal disease. Mannan-binding lectin Mannose-binding lectin (MBL), also called mannose-binding protein or mannan-binding protein (MBP), is a lectin that is instrumental in innate immunity via the lectin pathway. MBL has an
Keratin Cells in the epidermis contain a structural matrix of keratin, which makes this outermost layer of the skin almost waterproof, and along with collagen and elastin, gives skin its strength. Rubbing and pressure cause thickening of the outer, cornified layer of the epidermis and form protective calluses, which is useful for athletes and on the fingertips of musicians who play stringed instruments. Keratinized epidermal cells are constantly shed and replaced. These hard, integumentary structures are formed by intercellular cementing of fibers formed from the dead, cornified cells generated by specialized beds deep within the skin. Hair grows continuously and feathers
