Cell (biology) made up of cellulose, fungi cell walls are made up of chitin and bacteria cell walls are made up of peptidoglycan. A gelatinous capsule is present in some bacteria outside the cell membrane and cell wall. The capsule may be polysaccharide as in pneumococci, meningococci or polypeptide as "Bacillus anthracis" or hyaluronic acid as in streptococci. Capsules are not marked by normal staining protocols and can be detected by India ink or methyl blue; which allows for higher contrast between the cells for observation. Flagella are organelles for cellular mobility. The bacterial flagellum stretches from cytoplasm through the cell membrane(s)
Glial cell line-derived neurotrophic factor Vitamin D potently induces GDNF expression. Exposure of dopaminergic-like cell line to Ibogaine HCl results in an increase in GDNF mRNA, leading to protein expression and to the corresponding activation of the GDNF signaling pathway. This, in turn, leads to a further increase in the mRNA level of the growth factor through a feed-back loop. It was also found that ibogaine metabolite, noribogaine, also possess the ability to increase GDNF levels. Glial cell line-derived neurotrophic factor Glial cell-derived neurotrophic factor (GDNF) is a protein that, in humans, is encoded by the "GDNF" gene. GDNF is a small protein that potently
