M cell

He found that there was selected damage to M cells and P cells.

A nasik magic tesseract would have 40 lines passing through each of it's m cells.

Covering Peyer's patches are a layer of cells called M cells.

M cells may be more vulnerable to such damage, Dr. Quigley said, although exact mechanisms have not been worked out.

M cells (transient cells), are active only during stimulus onset and stimulus offset.

These host cells are generally M cells and Peyer's patches of the intestinal mucosa.

They are called magnocells and parvo cells - M cells and P cells for short.

Many M cells and P cells would be choked off, he said, unable to send or receive nourishing substances through the nerve fibers.

"When you lose M cells, the whole M cell system goes down," but the brain compensates and people hardly notice it.

M cells (or microfold cells) are cells found in the follicle-associated epithelium of the Peyer's patch.

Unfortunately, when M cells bring M. paratuberculosis to the Peyer's patch, the bacteria find an ideal place for growth.

Blood capillaries are a well-known site for transcytosis, though it occurs in other cells, including neurons, osteoclasts and M cells of the intestine.

M cells within the Peyer's patches physically transport the insoluble whole glucan particles into the gut-associated lymphoid tissue.

Electric potential coming from a particular part of the myocardium is the result of variation in electric charge density including endocardium, M cells and epicardium.

Parasol cell (Magnocellular, or M pathway; M cells)

M cells differ from normal enterocytes in that they lack microvilli on their apical surface, but instead possess broader microfolds that give the cell its name.

Dr. Glovinsky designed a handheld device that tests the eye for M cell function, Dr. Quigley said.

In the case of intestinal MALT, M cells are also present, which sample antigen from the lumen and deliver it to the lymphoid tissue.

Similarly, M cells detect medium wavelength colors, such as green and yellow, and L cells detect long wavelength colors, like red.

To prove that M cell loss predicts who will go on to develop glaucoma, Dr. Quigley and his colleagues are following 800 patients with elevated eye pressure for 10 years.

If the M cells are being destroyed early, Dr. Quigley said, "we wondered if we could detect it, before damage progressed to the rest of the optic nerve."

Layer one (1) contains M cells which correspond to the M (magnocellular) cells of the optic nerve of the opposite eye and are concerned with depth or motion.

M cells do not secrete mucus or digestive enzymes, and have a thinner glycocalyx, which allows them to have easy access to the intestinal lumen for endocytosis of antigens.

EPEC containing plasmids with genes for EAF (Escherichia coli Adherence Factor) will adhere to M cells.

Factors promoting the differentiation of M cells have yet to be elucidated, but they are thought to develop in response to signals from immune cells found in the developing Peyer's patch.
