Alemtuzumab
Alemtuzumab, sold under the brand names Campath and Lemtrada among others, is a medication used to treat chronic lymphocytic leukemia and multiple sclerosis. In chronic lymphocytic leukemia, it has been used as both a first line and second line treatment. It is given by injection into a vein. It is a monoclonal antibody that binds to CD52, a protein present on the surface of mature lymphocytes, but not on the stem cells from which these lymphocytes are derived. After treatment with alemtuzumab, these CD52-bearing lymphocytes are targeted for destruction. Alemtuzumab was approved for medical use in the United States in 2001. (Mab)Campath was withdrawn from the markets in the US and the EU in 2012, to prepare for a higher-priced relaunch of Lemtrada aimed at multiple sclerosis. Medical uses Chronic lymphocytic leukemia Alemtuzumab is used for the treatment of B-cell chronic lymphocytic leukemia in people who have been treated with alkylating agents and who have failed flud ...

CD52
CAMPATH-1 antigen, also known as cluster of differentiation 52 (CD52), is a glycoprotein that in humans is encoded by the ''CD52'' gene. CD52 is present on the surface of mature lymphocytes, but not on the stem cells from which these lymphocytes were derived. It also is found on monocytes and dendritic cells. Further, it is found within the male genital tract and is present on the surface of mature sperm cells. CD52 is a peptide of 12 amino acids, anchored to glycosylphosphatidylinositol (GPI). Since it is highly negatively charged and present on sperm cells and lymphocytes, it has been conjectured that its function is anti-adhesion, allowing cells to freely move around. CD52 binds the ITIM (immunoreceptor tyrosine-based inhibitory motif)-bearing sialic acid-binding lectin SIGLEC10. Clinical significance It is associated with certain types of lymphoma. It is the protein targeted by alemtuzumab, a monoclonal antibody used for the treatment of chronic lymphocytic leukemia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronic Lymphocytic Leukemia
Chronic lymphocytic leukemia (CLL) is a type of cancer that affects the blood and bone marrow. In CLL, the bone marrow makes too many lymphocytes, which are a type of white blood cell. In patients with CLL, B cell lymphocytes can begin to collect in their blood, spleen, lymph nodes, and bone marrow. These cells do not function well and crowd out healthy blood cells. CLL is divided into two main types: # Slow-growing CLL (indolent CLL) # Fast-growing CLL Many people do not have any symptoms when they are first diagnosed. Those with symptoms (about 5-10% of patients with CLL) may experience the following: * Fevers * Fatigue * Night sweats * Unexplained weight loss * Loss of appetite * Painless lymph node swelling * Splenomegaly, Enlargement of the spleen, and/or * A anemia, low red blood cell count (anemia). These symptoms may worsen over time. While the exact cause of CLL is unknown, having a family member with CLL increases one's risk of developing the disease. Environmental ...

Multiple Sclerosis
Multiple sclerosis (MS) is an autoimmune disease resulting in damage to myelinthe insulating covers of nerve cellsin the brain and spinal cord. As a demyelinating disease, MS disrupts the nervous system's ability to Action potential, transmit signals, resulting in a range of signs and symptoms, including physical, cognitive disability, mental, and sometimes psychiatric problems. Symptoms include double vision, vision loss, eye pain, muscle weakness, and loss of Sensation (psychology), sensation or coordination. MS takes several forms, with new symptoms either occurring in isolated attacks (relapsing forms) or building up over time (progressive forms). In relapsing forms of MS, symptoms may disappear completely between attacks, although some permanent neurological problems often remain, especially as the disease advances. In progressive forms of MS, bodily function slowly deteriorates once symptoms manifest and will steadily worsen if left untreated. While its cause is unclear, ...

Monoclonal Antibody
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell. Monoclonal antibodies are identical and can thus have monovalent affinity, binding only to a particular epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies are mixtures of antibodies derived from multiple plasma cell lineages which each bind to their particular target epitope. Artificial antibodies known as bispecific monoclonal antibodies can also be engineered which include two different antigen binding sites ( FABs) on the same antibody. It is possible to produce monoclonal antibodies that specifically bind to almost any suitable substance; they can then serve to detect or purify it. This capability has become an investigative tool in biochemistry, molecular biology, and medicine. Monoclonal antibod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greg Winter
Sir Gregory Paul Winter (born 14 April 1951) is a Nobel Prize-winning British molecular biologist best known for his work on the therapeutic use of monoclonal antibodies. His research career has been based almost entirely at the MRC Laboratory of Molecular Biology and the MRC Centre for Protein Engineering, in Cambridge, England. He is credited with the invention of techniques to both humanize (1986) and, later, to fully humanize using phage display, antibodies for therapeutic uses.ThScientific Founders of Bicycle Therapeutics Ltd. – Christian Heinis and Sir Greg Winter, FRS. Previously, antibodies had been derived from mice, which made them difficult to use in human therapeutics because the human immune system had anti-mouse reactions to them. For these developments Winter was awarded the 2018 Nobel Prize in Chemistry along with George Smith and Frances Arnold. He is a Fellow of Trinity College, Cambridge and was appointed Master of Trinity College, Cambridge on 2 Octo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bayer AG
Bayer AG (English: , commonly pronounced ; ) is a German multinational pharmaceutical and biotechnology company and is one of the largest pharmaceutical companies and biomedical companies in the world. Headquartered in Leverkusen, Bayer's areas of business include: pharmaceuticals, consumer healthcare products, agricultural chemicals, seeds and biotechnology products. The company is a component of the EURO STOXX 50 stock market index.

Off-label Use
Off-label use is the use of pharmaceutical drugs for an unapproved indication or in an unapproved age group, dosage, or route of administration. Both prescription drugs and over-the-counter drugs (OTCs) can be used in off-label ways, although most studies of off-label use focus on prescription drugs. Off-label use is very common and generally legal unless it violates ethical guidelines or safety regulations. The ability to prescribe drugs for uses beyond the officially approved indications is commonly used to good effect by healthcare providers. For example, methotrexate is commonly used off-label because its immunomodulatory effects relieve various disorders. However, off-label use can entail health risks and differences in legal liability. Marketing of pharmaceuticals for off-label use is usually prohibited. Indications and labeling laws An '' indication'' is when a drug is medically appropriate for a given condition; an approved indication is when a government drug regula ...

Graft-versus-host Disease
Graft-versus-host disease (GvHD) is a syndrome, characterized by inflammation in different organs. GvHD is commonly associated with bone marrow transplants and stem cell transplants. White blood cells of the donor's immune system which remain within the donated tissue (the graft) recognize the recipient (the host) as foreign (non-self). The white blood cells present within the transplanted tissue then attack the recipient's body's cells, which leads to GvHD. This should not be confused with a transplant rejection, which occurs when the immune system of the transplant recipient rejects the transplanted tissue; GvHD occurs when the donor's immune system's white blood cells reject the recipient. The underlying principle ( alloimmunity) is the same, but the details and course may differ. GvHD can also occur after a blood transfusion, known as ''Transfusion-associated graft-versus-host disease'' or TA-GvHD if the blood products used have not been gamma irradiated or treated ...
