Eotaxin
The eotaxins are a CC chemokine subfamily of eosinophil chemotactic proteins. Eotaxin is a special CC chemokine because it primarily attracts eosinophils. By being a chemoattractant for eosinophils, eotaxin has a direct relationship with inflammation. This is because eosinophils are known to promote inflammation. In order to induce stimulation, eotaxin binds with the CCR-3 receptor. The binding of eotaxin with the CCR-3 Receptor recruits eosinophils, which ultimately induces inflammation. According to early studies, the production of eotaxin can be linked to Th2 lymphocytes. Eotaxin appears to be T-cell dependent because of evidence that suggests that eosinophil recruitment is regulated by Th2 lymphocytes. The regulation occurs because of the presence of the CCR-3 Receptor on the Th2 lymphocyte. Some examples of the types of cells that have the ability of synthesizing eotaxin are lung cells, vascular endothelial cells, and macrophages. In humans, there are three family members: * ...

CCL11
C-C motif chemokine 11 also known as eosinophil chemotactic protein and eotaxin-1 is a protein that in humans is encoded by the CCL11 gene. This gene is encoded on three exons and is located on chromosome 17. Function CCL11 is a small cytokine belonging to the CC chemokine family. CCL11 selectively recruits eosinophils by inducing their chemotaxis, and therefore, is implicated in allergic responses. The effects of CCL11 are mediated by its binding to a G-protein-linked receptor known as a chemokine receptor. Chemokine receptors for which CCL11 is a ligand include CCR2, CCR3 and CCR5. However, it has been found that eotaxin-1 (CCL11) has high degree selectivity for its receptor, such that they are inactive on neutrophils and monocytes, which do not express CCR3. Clinical significance Increased CCL11 levels in blood plasma are associated with aging in mice and humans. Additionally, it has been demonstrated that exposing young mice to CCL11 or the blood plasma of older mice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CCL24
Chemokine (C-C motif) ligand 24 (CCL24) also known as myeloid progenitor inhibitory factor 2 (MPIF-2) or eosinophil chemotactic protein 2 (eotaxin-2) is a protein that in humans is encoded by the ''CCL24'' gene. This gene is located on human chromosome 7. Function CCL24 is a small cytokine belonging to the CC chemokine family. CCL24 interacts with chemokine receptor CCR3 to induce chemotaxis in eosinophils. This chemokine is also strongly chemotactic for resting T lymphocytes and slightly chemotactic for neutrophils. Clinical significance Elevated levels of eotaxin-2 has been seen in patients with aspirin-exacerbated respiratory disease Aspirin exacerbated respiratory disease (AERD), also termed aspirin-induced asthma, is a medical condition initially defined as consisting of three key features: asthma, respiratory symptoms exacerbated by aspirin and other nonsteroidal anti-inf ...

Chemokine
Chemokines (), or chemotactic cytokines, are a family of small cytokines or signaling proteins secreted by cells that induce directional movement of leukocytes, as well as other cell types, including endothelial and epithelial cells. In addition to playing a major role in the activation of host immune responses, chemokines are important for biological processes, including morphogenesis and wound healing, as well as in the pathogenesis of diseases like cancers. Cytokine proteins are classified as chemokines according to behavior and structural characteristics. In addition to being known for mediating chemotaxis, chemokines are all approximately 8-10 kilodaltons in mass and have four cysteine residues in conserved locations that are key to forming their 3-dimensional shape. These proteins have historically been known under several other names including the ''SIS family of cytokines'', ''SIG family of cytokines'', ''SCY family of cytokines'', ''Platelet factor-4 superfamily'' or ...

Eosinophil
Eosinophils, sometimes called eosinophiles or, less commonly, acidophils, are a variety of white blood cells (WBCs) and one of the immune system components responsible for combating multicellular parasites and certain infections in vertebrates. Along with mast cells and basophils, they also control mechanisms associated with allergy and asthma. They are granulocytes that develop during hematopoiesis in the bone marrow before migrating into blood, after which they are terminally differentiated and do not multiply. They form about 2 to 3% of WBCs. These cells are eosinophilic or "acid-loving" due to their large acidophilic cytoplasmic granules, which show their affinity for acids by their affinity to coal tar dyes: Normally transparent, it is this affinity that causes them to appear brick-red after staining with eosin, a red dye, using the Romanowsky method. The staining is concentrated in small granules within the cellular cytoplasm, which contain many chemical mediators, such ...

CCL26
Chemokine (C-C motif) ligand 26 (CCL26) is a small cytokine belonging to the CC chemokine family that is also called Eotaxin-3, Macrophage inflammatory protein 4-alpha (MIP-4-alpha), Thymic stroma chemokine-1 (TSC-1), and IMAC. It is expressed by several tissues including heart, lung and ovary, and in endothelial cells that have been stimulated with the cytokine interleukin 4. CCL26 is chemotactic for eosinophils and basophils and elicits its effects by binding to the cell surface chemokine receptor CCR3. This gene for chemokine is located on human chromosome 7 Chromosome 7 is one of the 23 pairs of chromosomes in humans, who normally have two copies of this chromosome. Chromosome 7 spans about 159 million base pairs (the building material of DNA) and represents between 5 and 5.5 percent of the total D ....Hillier et al. The DNA sequence of human chromosome 7.

Chemotactic
Chemotaxis (from '' chemo-'' + ''taxis'') is the movement of an organism or entity in response to a chemical stimulus. Somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (e.g., glucose) by swimming toward the highest concentration of food molecules, or to flee from poisons (e.g., phenol). In multicellular organisms, chemotaxis is critical to early development (e.g., movement of sperm towards the egg during fertilization) and development (e.g., migration of neurons or lymphocytes) as well as in normal function and health (e.g., migration of leukocytes during injury or infection). In addition, it has been recognized that mechanisms that allow chemotaxis in animals can be subverted during cancer metastasis. The aberrant chemotaxis of leukocytes and lymphocytes also contribute to inflammatory diseases such as atherosclerosis, asthma, and arthri ...

Hydropathy Plot Of Eotaxin
Hydrotherapy, formerly called hydropathy and also called water cure, is a branch of alternative medicine (particularly naturopathy), occupational therapy, and physiotherapy, that involves the use of water for pain relief and treatment. The term encompasses a broad range of approaches and therapeutic methods that take advantage of the physical properties of water, such as temperature and pressure, to stimulate blood circulation, and treat the symptoms of certain diseases. Various therapies used in the present-day hydrotherapy employ water jets, underwater massage and mineral baths (e.g. balneotherapy, Iodine-Grine therapy, Kneipp treatments, Scotch hose, Swiss shower, thalassotherapy) or whirlpool bath, hot Roman bath, hot tub, Jacuzzi, and cold plunge. Uses Water therapy may be restricted to use as aquatic therapy, a form of physical therapy, and as a cleansing agent. However, it is also used as a medium for delivery of heat and cold to the body, which has long been the ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
