To precisely target and eliminate cancer cells, monoclonal antibody therapy makes use of man-made antibodies. Oncologists, doctors who specialize in treating cancer, also employ monoclonal antibody therapy to improve the body’s defenses against malignancy. This therapy can be used independently or in combination with other therapies by providers.
What Exactly are Monoclonal Antibodies?
Antibodies are a component of your immune system. Antibodies are proteins that probe your body for evidence of foreign invaders (antigens), such as infections or cancer cells. Antibodies bind to (attach to) antigens. The immune system then creates strategies to safeguard your body from future invaders. Monoclonal antibodies are designed to mimic your antibodies.
What Effect do Monoclonal Antibodies Have on Cancer Cells?
Monoclonal antibodies are multitaskers that use a variety of ways to destroy cancer cells. Here are some examples of how monoclonal antibodies might be used:
They create immunological targets. Some monoclonal antibodies recognize and bind to cancer cells. This allows the immune system to more efficiently target and eliminates cancer cells.
They are equipped with specialized therapies. Some monoclonal antibodies deliver chemotherapeutic and radioactive chemicals to cancer cells. These are drug-antibody conjugates.
They interfere with cancer cell signaling. Specific cancer cells contain receptors that tell them to divide. Monoclonal antibodies block the signals, preventing cancer cells from multiplying.
Some monoclonal antibodies, for example, act by blocking signals from the cancer cell, known as the checkpoint system. Immune checkpoints prevent your immune system from responding to invaders and accidentally damaging healthy tissue. Cancer cells can disable the system by expressing checkpoint proteins on their surface to shield themselves from immune system attacks. Some monoclonal antibodies block these checkpoints, enabling your immune cells (such as T-cells) to kill cancer cells.
What Makes Monoclonal Antibodies (mAbs) so Promising in the War Against Cancer?
Surgery, chemotherapy, and radiation are all standard methods for treating cancer, but they might have unintended adverse effects on healthy cells and tissues. However, therapeutic mAbs are great medication candidates due to their target specificity. As a result, they have risen to the top of the pharmaceutical industry’s sales charts in recent decades. Because of the drugs’ pinpoint accuracy, we don’t see the same kinds of collateral damage as we would with chemotherapy drugs. In addition, a biomarker-specific mAb can be employed for different forms of cancer when the same target is overexpressed because many malignancies have similar biomarkers (e.g., EGFR). They may be created as antibody-drug-conjugates (ADCs) to convey very effective cytotoxic drugs to their target, and they are also quite adaptable in other ways. Bispecific is a distinct type of mAb because they interact with two targets simultaneously, such as a cancer cell and an immune cell. This therapy has shown a lot of promise in treating several tumors.
