The Caribbean Examinations Council (CXC) is an examination board in the Caribbean. [ 1 ] [ 2 ] It was established in 1972 [ 3 ] under agreement by the participating governments in the Caribbean Community to conduct such examinations as it may think appropriate and award certificates and diplomas on the results of any such examinations so conducted.
CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family. They represent one subfamily of chemokine receptors , a large family of G protein-linked receptors that are known as seven transmembrane (7-TM) proteins, since they span the cell membrane seven times.
The chemokine (C-X-C motif) ligand 1 (CXCL1) is a small peptide belonging to the CXC chemokine family that acts as a chemoattractant for several immune cells, especially neutrophils [5] [6] or other non-hematopoietic cells to the site of injury or infection and plays an important role in regulation of immune and inflammatory responses. It was ...
ELR-positive CXC chemokines specifically induce the migration of neutrophils, and interact with chemokine receptors CXCR1 and CXCR2. An example of an ELR-positive CXC chemokine is interleukin-8 (IL-8), which induces neutrophils to leave the bloodstream and enter into the surrounding tissue.
The National Certificate of Secondary Education is an examination that is held at the last week of June for form 3 students in Trinidad and Tobago, for entry into the upper secondary system for students to choose subjects for the Caribbean Certificate of Secondary Education Exam offer by the Caribbean Examinations Council (CXC).
CXC refers to the Caribbean Examinations Council, an exam board in the Caribbean. CXC can also refer to: 190 (number), in Roman numerals; 190 (year), a year in the second century; 190 (disambiguation), several topics; CXC chemokines, a type of signaling protein in biology; Chitina Airport, an airport near Chitina, Alaska, U.S.
Chemokine receptors are divided into different families, CXC chemokine receptors, CC chemokine receptors, CX3C chemokine receptors and XC chemokine receptors that correspond to the 4 distinct subfamilies of chemokines they bind. The four subfamilies of chemokines differ in the spacing of structurally important cysteine residues near the N ...
Chemokine (C-X-C motif) ligand 9 (CXCL9) is a small cytokine belonging to the CXC chemokine family that is also known as monokine induced by gamma interferon (MIG). The CXCL9 is one of the chemokine which plays role to induce chemotaxis, promote differentiation and multiplication of leukocytes, and cause tissue extravasation.
