Nectin-4
Nectins and Nectin-like molecules (Necl) are families of cellular adhesion molecules involved in Ca2+-independent cellular adhesion. Nectins are ubiquitously expressed and have adhesive roles in a wide range of tissues such as the adherens junction of epithelia or the chemical synapse of the neuronal tissue. Diversity So far four nectins have been identified in humans, namely nectin-1, nectin-2, nectin-3 and nectin-4. These four family members have also been found in most other well studied mammals. Also, five Necls have been identified, these are: Necl-1, Necl-2, Necl-3, Necl-4 and Necl-5. Structure All nectins and all Necls share the same overall structure defined by three extra cellular immunoglobulin domains, a single transmembrane helix and an intracellular domain. For all nectins the intracellular domain can bind a scaffold protein named afadin (the product of the MLLT4 gene). All nectins and Necls can form homo-cis dimers, meaning a dimer of two alike molecules o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Enfortumab Vedotin
Enfortumab vedotin, sold under the brand name Padcev, is an antibody-drug conjugate used for the treatment of urothelial cancer. It is a nectin-4-directed antibody and microtubule inhibitor conjugate. Enfortumab refers to the monoclonal antibody part, and vedotin refers to the payload drug (MMAE) and the linker. The most common side effects include fatigue, peripheral neuropathy (nerve damage resulting in tingling or numbness), decreased appetite, rash, alopecia (hair loss), nausea, altered taste, diarrhea, dry eye, pruritus (itching) and dry skin. The fully humanized antibody was created by scientists at Agensys (part of Astellas) using Xenomice from Amgen; the linker technology holding the antibody and the toxin together was provided by and licensed from Seattle Genetics. The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication. Medical uses Enfortumab vedotin is indicated for the treatment of adults with locally advanced (when cancer has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD155
CD155 (cluster of differentiation 155) also known as the poliovirus receptor is a protein that in humans is encoded by the ''PVR'' gene. Function CD155 is a Type I transmembrane glycoprotein in the immunoglobulin superfamily. Commonly known as ''Poliovirus Receptor'' (PVR) due to its involvement in the cellular poliovirus infection in primates, CD155's normal cellular function is in the establishment of intercellular adherens junctions between epithelial cells. The role of CD155 in the immune system is unclear, though it may be involved in intestinal humoral immunity, humoral immune responses. Subsequent data has also suggested that CD155 may also be used to positively select MHC restriction, MHC-independent T cells in the thymus. The external domain mediates cell attachment to the extracellular matrix molecule vitronectin, while its intracellular domain interacts with the dynein light chain Tctex-1/DYNLT1. The gene is specific to the primate lineage, and serves as a cellular r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lung Cancer 1
The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the air and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their different muscles to support and foster breathing. In earlier tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, a mechanism still seen in amphibians. In humans, the main muscle of respiration that drives breathing is the diaphragm. The lungs also provide airflow that makes vocal sounds including human speech possible. Humans have two lungs, one on the left and one on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
