Amacrine cell Amacrine cells operate at the inner plexiform layer (IPL), the second synaptic retinal layer where bipolar cells and retinal ganglion cells form synapses.There are at least 33 different subtypes of amacrine cells based just on their dendrite morphology and stratification.macrine cells are inhibitory neurons, and project their dendritic arbors to the inner plexiform layer (IPL), there interacting with retinal ganglion cells and/or bipolar cells.

Enteroendocrine cell Enteroendocrine cell. Enteroendocrine cells are specialized cells of the gastrointestinal tract and pancreas with endocrine function. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous responses. Enteroendocrine cells of the intestine are the most numerous endocrine cells of the body. They constitute an enteric endocrine system a

- A peripheral blood mononuclear cell (PBMC) is any blood cell having a round nucleus (as opposed to a lobed nucleus). For example: a lymphocyte or a monocyte. These blood cells are a critical component in the immune system to fight infection and adapt to intruders.

Champter 1-7 Paracrine communication is when endocrine cells release hormones that act on adjacent target cells. Endocrine communication is when endocrine cells release hormones into the bloodstream and these hormones then travel via blood circulation to distant target cells.

Echinocyte From Wikipedia, the free encyclopedia. Echinocyte (from the Greek word echinos, meaning 'hedgehog' or 'sea urchin'), in human biology and medicine, refers to a form of red blood cell that has an abnormal cell membrane characterized by many small, evenly spaced thorny projections.A more common term for these cells is burr cells.chinocytes, like acanthocytes, may be found in hyperlipidemia caused by liver dysfunction, but the lipids themselves do not integrate into the membrane. Instead, it is speculated that cell surface receptors on the red blood cells bind with HDL cholesterol which induces the shape change.

Antigen-presenting cell An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs).

Glossary of HIV/AIDS-related Terms: A peripheral blood mononuclear cell (PBMC) is defined as any blood cell with a round nucleus (i.e. a lymphocyte, a monocyte, or a macrophage). These blood cells are a critical component in the immune system to fight infection and adapt to intruders.he lymphocyte population consists of T cells, B cells and Natural Killer cells. These cells are often extracted from whole blood or from leukopacks using ficoll, a hydrophilic polysaccharide that separates layers of blood, with monocytes and lymphocytes forming a buffy coat under a layer of plasma.

Amacrine cell In many cases, the subtype of the amacrine cell speaks to its function (form leads to function), but some specific functions of the retinal amacrine cells can be outlined. 1  Intercept retinal ganglion cells and/ or bipolar cells in the IPL.  Create functional subunits within the receptive fields of many ganglion cells.

Amacrine cell Medium field amacrine cells also contribute to vertical communication in the cells of the retina, but much of their overall function is still unknown. Due to the fact that their dendritic arbor size is pretty similar to that of ganglion cells, they could blur the edge of the ganglion cell visual field.here is still much to be discovered about all of the different functions of all of the different amacrine cells. Amacrine cells with extensive dendritic trees are thought to contribute to inhibitory surrounds by feedback at both the bipolar cell and ganglion cell levels.

Breast Apocrine Metaplasia Apocrine metaplasia is sometimes described as a ‘benign epithelial alteration’ of breast tissue, which means that epithelial cells are undergoing an unexpected change. The word apocrine means something to do with sweat, but only a resemblance. It’s not actually sweat gland related.pocrine metaplasia is a ‘ non-proliferative ‘ breast lesion, and is usually associated with breast fibrocystic disease. The term “proliferative” would mean that cells are growing and growing, and in a somewhat unpredictable way. Proliferative cells growth is therefore usually associated with carcinoma.

M cells transport antigens from the intestinal lumen to the underlying lymphoid tissues for recognition and processing. cell whose function is to reproduce the organism. Early in development, primordial germ cells are found in the genital ridges of the embryo. Later, in the testis, the primordial germ cells are called spermatogonia, and in the ovary, they are called oogonia.

- Intestinal Absorptive Cells. Absorptive cells, or enterocytes, are the predominant epithelial cell type lining the lumen of the small intestine and colon. These cells are specialized for absorption of nutrients across the apical plasma membrane and export of these same nutrients across the basal plasma membrane.

Definitions &Translations The mononuclear phagocyte system (MPS) (also called Reticuloendothelial System or Macrophage System) is a part of the immune system that consists of the phagocytic cells located in reticular connective tissue.The cells are primarily monocytes and macrophages, and they accumulate in lymph nodes and the spleen.he spleen is the largest unit of the mononuclear phagocyte system. The monocyte is formed in the bone marrow and transported by the blood; it migrates into the tissues, where it transforms into a histiocyte or a macrophage.
