An oncolytic virus is a virus that preferentially infects and kills cancer cells. As the infected cancer cells are destroyed by oncolysis, they release new infectious virus particles or virions to help destroy the remaining tumour. Oncolytic viruses are thought not only to cause direct destruction of the tumour cells, but also to stimulate host ...
Tumor-associated immune cells in the tumor microenvironment (TME) of breast cancer models. Cancer immunology (immuno-oncology) is an interdisciplinary branch of biology and a sub-discipline of immunology that is concerned with understanding the role of the immune system in the progression and development of cancer; the most well known application is cancer immunotherapy, which utilises the ...
Antagonistic antibodies, also called immune checkpoints inhibitors, obstruct the binding between cancer cells and immune checkpoints to antagonize cancer cells’ action and restore immune surveillance. Therefore, immune cells can recognize the surface antigens on the tumor cells to elicit immune responses.
Antibody drug conjugates, on the other hand, are designed to attack only cancer cells, thanks to the addition of specialized monoclonal antibodies that seek out specific targets on the cancer cells.
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.

The cells are expanded non-specifically and/or stimulated. The cells are then reinfused and produce an immune response against the tumour cells. [34] The technique has been tested on refractory stage IV metastatic melanomas [33] and advanced skin cancer. [35] [36] [37] The first FDA-approved CAR-T drug, Kymriah, used this approach. To obtain ...
B cells can produce antibodies that recognize and neutralize cancer cells. [5] However, cancer cells can evade immune surveillance and escape destruction by the immune system through various mechanisms, including downregulating antigen presentation, producing immunosuppressive molecules, and inhibiting T cell function.
Tumor cells, however are highly abnormal, and many display unusual antigens. Some such tumor antigens are inappropriate for the cell type or its environment. Monoclonal antibodies can target tumor cells or abnormal cells in the body that are recognized as body cells, but are debilitating to one's health. [citation needed]
