The term “CART drug” often leads to confusion because it refers to two completely different biological entities. These distinct meanings arise from their acronyms, which happen to be very similar. This article aims to clarify these two separate concepts, explaining their unique mechanisms, applications, and the scientific research surrounding them. Understanding the context in which “CART drug” is used is important to discern its intended meaning.
CART Peptides
CART peptides, an abbreviation for Cocaine- and Amphetamine-Regulated Transcript, are small protein molecules that function as neuromodulators, regulating various physiological processes. They are found extensively in the central nervous system, as well as in the pituitary and adrenal glands, the pancreas, and the gut.
CART peptides are involved in controlling food intake and maintaining body weight. They also participate in reward pathways, brain circuits associated with pleasure and motivation, and are implicated in drug abuse. Additionally, CART peptides influence endocrine functions, stress responses, and cardiovascular activity.
Research explores CART peptides’ roles in health conditions. Studies suggest their involvement in drug addiction and eating disorders. They also participate in anxiety-like behaviors, with genetic mutations in the CART gene associated with increased anxiety and depression.
CAR T-Cell Therapy
CAR T-cell therapy, which stands for Chimeric Antigen Receptor T-cell therapy, is a form of immunotherapy used primarily in cancer treatment. This approach involves modifying a patient’s own immune cells to target and eliminate cancer cells. The process begins with collecting T cells, a type of white blood cell, from the patient’s blood.
Once collected, these T cells are genetically engineered. A new gene is introduced, enabling them to produce a specialized protein called a Chimeric Antigen Receptor (CAR). This CAR acts as a specific receptor, allowing the modified T cells to recognize and bind to specific antigens found on the surface of cancer cells.
After genetic modification, these CAR T cells are multiplied in large numbers to create a “living drug.” The amplified CAR T cells are then infused back into the patient’s bloodstream. Once inside the body, these engineered T cells seek out and destroy cancer cells that display the targeted antigen, offering a personalized and precise treatment approach.
CAR T-cell therapy has demonstrated success, particularly in treating certain blood cancers. It is an approved treatment option for specific types of leukemia, lymphoma, and multiple myeloma. While its application in solid tumors presents ongoing challenges due to the complex tumor environment, research continues to explore its potential in these cancers and even in autoimmune diseases.
Two Distinct Meanings
Their full names indicate their differing origins and functions: “CART peptides” (Cocaine- and Amphetamine-Regulated Transcript) refer to naturally occurring neuromodulators, while “CAR T-cell therapy” (Chimeric Antigen Receptor T-cell therapy) describes a form of cellular immunotherapy.
Context is important for accurate interpretation. If the discussion pertains to brain function, appetite regulation, or addiction research, it refers to CART peptides. If the topic involves cancer treatment, genetic engineering of immune cells, or immunotherapy, it refers to CAR T-cell therapy. These concepts operate in different biological and medical domains and are not interchangeable.
