Sugemalimab, sold under the brand name Cejemly among others, is a monoclonal antibody used for the treatment of metastatic non-small cell lung cancer (NSCLC) in combination with chemotherapy. [1] It is an antineoplastic monoclonal antibody that potentiates T-cell responses, including anti-tumor responses, through blockade of PD-1 binding to PD ...
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system. Immunotherapy is designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies .
Antigenic escape, immune escape, immune evasion or escape mutation occurs when the immune system of a host, especially of a human being, is unable to respond to an infectious agent: the host's immune system is no longer able to recognize and eliminate a pathogen, such as a virus.
Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. [1] It is an application of the fundamental research of cancer immunology (immuno-oncology) and a growing subspecialty of oncology.
In the future, the use or knockouts of immunoevasins (where mutated or deleted immunoevasin genes would not interfere with antigen presentation on MHC I complexes upon viral infection, resulting in recognition and targeting of infected cells by T cells) may be used for vaccine development for HCMV, gene therapy, transplantation and tumor ...
Current strategies for the treatment of T-cell mediated pathologies employ long-term, broad immunosuppressive drugs, which are moderately effective in limiting T-cell responses but carry unfavorable side effects, such as organ toxicity, risk of infection, and cancer. [3]
Interleukin-2 is an important immune system regulator necessary for the clone expansion and survival of activated lymphocytes T. Its effects are mediated by the trimer cell surface receptor IL-2a, consisting of the α, β, and γ chains. The IL-2a (CD25, T-cell activation antigen, TAC) is expressed only by the already-activated T lymphocytes.
Positive immunostaining can predict response to the treatment. PD-1 inhibitors and PD-L1 inhibitors are a group of checkpoint inhibitor anticancer drugs that block the activity of PD-1 and PDL1 immune checkpoint proteins present on the surface of cells. Immune checkpoint inhibitors are emerging as a front-line treatment for several types of ...
