Introduction

Immunotherapy refers to a group of cancer treatments that activate the body's immune system to combat cancer cells. Cancer cells differ from regular cells in that they do not die in the same way that normal cells do. They divide at a breakneck speed, like an out-of-control copy machine that won't stop making copies [1].

Description

These aberrant cells regularly change, or mutate, in order to avoid being detected by the immune system, which defends the body from sickness and infection. Cancer immunotherapy medications work by alerting the immune system to the presence of these altered cells, allowing it to track them down and eliminate them [2].

Researchers discovered that INF-alfa, a form of interferon, can boost your immune response to cancer cells by activating particular white blood cells including natural killer cells and dendritic cells. INF-alfa may potentially inhibit the growth or induce the death of cancer cells. There are over a dozen different interleukins, including IL-2, also known as T-cell growth factor. IL-2 increases the number of white blood cells, such as killer T cells and natural killer cells, in the body. Increased numbers of these cells may trigger an immunological response against malignancy. IL-2 also facilitates the production of specific chemicals that can kill cancer cells by B cells (another type of white blood cell).

Immune modulation in cancer refers to a variety of treatments aiming at harnessing a patient's immune system in order to achieve tumour management, stabilisation, and maybe disease eradication. Immune checkpoint-blocking antibodies are a new therapeutic medication class that modulates T-cell pathways that govern T cells and has the potential to renew an antitumour immune response. Ipilimumab was the first FDA-approved immune checkpoint antibody for the treatment of metastatic melanoma (MM), and it works by blocking a checkpoint protein known as cytotoxic T-lymphocyte antigen 4 (CTLA-4) (CTLA-4).

Immune-modulating drugs can have negative side effects that affect people differently. The type of cancer you have, how advanced it is, the type of immune-modulating medication you are given, and the dose will all influence the side affects you experience and how they make you feel. Doctors and nurses have no way of knowing when or whether side effects will emerge, let alone how severe they will be. As a result, it's critical to understand what to look for and what to do if difficulties arise [3].

Bacillus Calmette-Guérin (BCG) is a bacteria that does not cause disease in humans, but it does infect human tissues and aids in immune system activation. As a result, BCG can be used as a cancer immunotherapy. BCG was one of the first cancer immunotherapies, and it's still being used today.

BCG is a vaccine that is used to treat bladder cancer in its early stages. It's a liquid that's injected into the bladder using a catheter. BCG draws immune system cells to the bladder, allowing them to fight cancer cells there. BCG treatment can cause symptoms similar to the flu, such as fever, chills, and exhaustion. It can also give you a burning sensation in your bladder. Immune checkpoint inhibitors are medications that allow your immune system to function normally. Eight of these medications have been approved for cancer treatment. To let immune cells go after malignant development, they block the proteins PD-1, PD-L1, CTLA-4, and TF on their surface [4,5].

Conclusion

The most prevalent type of monoclonal antibody utilised in cancer treatment is naked monoclonal antibodies. Because they are unconnected to anything, they are referred to as naked. These antibodies either enhance your immune system's reaction to cancer or prevent antigens that aid cancer growth and spread. A chemotherapeutic medication or a radioactive particle is coupled to conjugated monoclonal antibodies. The antibodies bind to malignant cells directly. This helps chemotherapy and radiation therapies operate better by reducing side effects.
