Cyclophosphamide (CP), also known as cytophosphane among other names, [3] is a medication used as chemotherapy and to suppress the immune system. [4] As chemotherapy it is used to treat lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer, small cell lung cancer, neuroblastoma, and sarcoma. [4]
They include T cells and B cells and are part of the larger category of ‘tumor-infiltrating immune cells’ which consist of both mononuclear and polymorphonuclear immune cells, (i.e., T cells, B cells, natural killer cells, macrophages, neutrophils, dendritic cells, mast cells, eosinophils, basophils, etc.) in variable proportions. Their ...
Depletion of regulatory T cells increases immune activation. Glut1 regulation is associated with the activation of CD4+ T cells, thus its expression can be used to track the loss of CD4+ T cells during HIV. [19] Antiretroviral therapy, the most common treatment for patients with HIV, has been shown to restore CD4+ T cell counts. [20]
Regulatory T cell, a target of metronomic therapy, can suppress other immune cells. Tumor cells develop various means to evade immunosurveillance of the host. [9] The number of CD4+ CD25+ FOXP3+ regulatory T cells (Tregs) was found to increase in various types of tumors, suppressing both specific and innate immune responses. [5]
T-cell ALL responds to cyclophosphamide-containing agents the most. [ 49 ] Recent updates on the treatment of adult acute lymphoblastic leukemia (ALL) include advancements in immunotherapy, particularly the use of monoclonal antibodies like blinatumomab and inotuzumab ozogamicin, which target specific cancer cells and are used alongside stem ...
Cells from the immune system also make crucial contributions to the antitumor effects of chemotherapy. [163] For example, the chemotherapeutic drugs oxaliplatin and cyclophosphamide can cause tumor cells to die in a way that is detectable by the immune system (called immunogenic cell death), which mobilizes immune cells with antitumor functions ...
Anti-thymocyte globulin (ATG) is an infusion of horse or rabbit-derived antibodies against human T cells and their precursors , which is used in the prevention and treatment of acute rejection in organ transplantation and therapy of aplastic anemia due to bone marrow insufficiency.
Cellular immunity protects the body through: T-cell mediated immunity or T-cell immunity: activating antigen-specific cytotoxic T cells that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens;
