The Role of the Immune System in Cancer Treatment
The immune system plays a key role in fighting cancer. It uses its own powers to find and kill cancer cells. This helps keep us healthy and fight off diseases.
Immune System Basics
The immune system is made up of many cells, tissues, and organs. They work together to keep us safe from infections and diseases. White blood cells like lymphocytes and macrophages are key in fighting off bad cells.
They help keep our bodies safe from harmful things like bacteria, viruses, and cancer cells.
How the Immune System Targets Cancer
The immune system is very good at finding and fighting cancer. It uses things like antigen presentation and immune checkpoints to watch for abnormal cells. When it finds cancer cells, it sends immune cells to get rid of them.
Exploring Types of Immunotherapy for Cancer Treatment This is why understanding how the immune system works is important. It helps make treatments that boost our immune system to fight cancer better.
Monoclonal Antibodies in Cancer Immunotherapy
Monoclonal antibodies are a big step forward in fighting cancer. They target cancer cells very precisely. These special molecules stick to certain proteins on cancer cells. This makes the immune system attack the cancer or stop it from growing.
Monoclonal antibodies work as targeted treatments. They hit cancer cells but leave healthy cells alone. This means fewer side effects compared to old treatments like chemotherapy and radiation.
Some top treatments use monoclonal antibodies. For example, Rituxan (rituximab) goes after CD20 proteins on some B cells. Herceptin (trastuzumab) targets HER2 receptors in some breast cancers. These antibodies stop cancer cells from growing and help the immune system fight the tumors.
Exploring Types of Immunotherapy for Cancer Treatment Monoclonal antibodies have changed cancer treatment a lot. They’ve led to better survival rates and a better life for patients. By focusing on specific targets, these drugs offer a more tailored and effective way to fight cancer.

| Herceptin (trastuzumab) | HER2 | Breast cancer | Inhibits HER2 receptor signaling |
| Avastin (bevacizumab) | VEGF | Colorectal cancer | Prevents angiogenesis |
| Keytruda (pembrolizumab) | PD-1 | Melanoma | Blocks PD-1 pathway, reactivates T cells |
Immune Checkpoint Inhibitors
Immune checkpoint inhibitors have changed how we treat cancer. They work by lifting the brakes on our immune system. This lets our immune system attack cancer cells better.
How Checkpoint Inhibitors Work
Our immune system has ways to stop it from attacking healthy cells. But cancer cells can use these to hide. Checkpoint inhibitors block these brakes. This lets the immune system see and destroy cancer cells. They focus on the PD-1/PD-L1 and CTLA-4 pathways.
Common Checkpoint Inhibitors Drugs
Many drugs have been made to stop these immune checkpoints. PD-1 inhibitors and CTLA-4 inhibitors are some. They work well against cancers like melanoma, lung cancer, and kidney cancer.
| Drug Name | Target | Approved Indications |
|---|---|---|
| Nivolumab (Opdivo) | PD-1 inhibitor | Melanoma, Lung Cancer, Renal Cell Carcinoma |
| Pembrolizumab (Keytruda) | PD-1 inhibitor | Melanoma, Lung Cancer, Hodgkin’s Lymphoma |
| Ipilimumab (Yervoy) | CTLA-4 inhibitor | Melanoma, Renal Cell Carcinoma |
| Atezolizumab (Tecentriq) | PD-L1 inhibitor | Bladder Cancer, Lung Cancer |
These new treatments show how powerful our immune system can be against cancer. As we keep researching, more people will get help. This gives hope to many around the world.
Adoptive Cell Transfer in Immunotherapy
Adoptive cell therapy (ACT) is a new way to fight cancer. It uses the patient’s own immune cells to attack cancer. First, immune cells are taken out. Then, they are grown and made stronger outside the body. Finally, they are put back into the patient.
CAR T-cell therapy is a key part of ACT. It changes a patient’s T-cells to find and attack cancer cells. This makes a treatment that fits the patient’s cancer well.
Here’s how adoptive cell therapy works:
- Isolation of immune cells: T-cells are taken from the patient’s blood.
- Genetic modification: For CAR T-cell therapy, T-cells get CARs that find cancer cells.
- Cell expansion: The modified T-cells grow in the lab to fight cancer.
- Reinfusion: These T-cells are given back to the patient to attack cancer cells.
Studies show that adoptive cell therapy, like CAR T-cell therapy, works well against blood cancers. Researchers are now trying to make it work against solid tumors too.
Adoptive cell therapy, especially CAR T-cell therapy, shows how our immune system can fight cancer. As scientists learn more, these treatments could change how we treat cancer.
Cancer Vaccines
Cancer vaccines are a new way to fight cancer. They help the body fight cancer before or after it starts. These vaccines work by making the immune system stronger. This can help prevent cancer or treat it.
Exploring Types of Immunotherapy for Cancer Treatment There are two kinds of cancer vaccines. One type helps stop cancer from happening. The other type helps treat cancer that is already there. Each type works in a different way to help the body fight cancer.
Let’s look at some examples of these vaccines. They are making a big difference in the fight against cancer.
Preventive vs. Therapeutic Cancer Vaccines
Preventive cancer vaccines stop cancer before it starts. They target things that can cause cancer. For example, the HPV vaccine stops human papillomavirus from causing cervical cancer.
Therapeutic cancer vaccines work on cancer that is already there. They help the immune system fight the cancer. Sipuleucel-T is one example. It helps fight prostate cancer.
Examples of Cancer Vaccines
Cancer vaccines are leading the way in fighting cancer. They are both preventive and therapeutic.
- HPV Vaccine: This vaccine helps prevent cervical and other cancers caused by HPV.
- Sipuleucel-T: This vaccine is for prostate cancer. It helps the immune system fight the cancer.
Researchers are always working on new cancer vaccines. They want to find more ways to help the immune system fight cancer. This could lead to even better treatments in the future.
Let’s compare some cancer vaccines to see how they differ:
| Vaccine Type | Examples | Target | Objective |
|---|---|---|---|
| Preventive | HPV Vaccine | Human papillomavirus | Prevent virus-related cancers |
| Therapeutic | Sipuleucel-T | Prostate cancer antigens | Treat existing cancer |
Oncolytic Virus Therapy
Oncolytic virus therapy is a new way to fight cancer. It uses viruses to target and kill cancer cells. This method is exciting because it works in two ways. It directly kills cancer cells and helps the immune system fight tumors.
This therapy works because viruses can tell cancer cells from healthy ones. When a virus infects a cancer cell, it grows inside and kills the cell. This way, it destroys the tumor without harming healthy cells.
Some viruses are being tested in hospitals. For example, T-VEC is a virus that has been approved for melanoma. It kills cancer cells and helps the immune system fight tumors.
Below is a table showing some oncolytic viruses being tested: Exploring Types of Immunotherapy for Cancer Treatment
| Oncolytic Virus | Origin | Target Cancer | Approval Status |
