What Is 
immunotherapy?
● Definition: Immunotherapy uses the body’s immune 
system to fight cancer.
● It harnesses or enhances the immune system’s natural 
ability to detect and destroy cancer cells.
● A variety of immunotherapies exist, including Car T Cell 
Therapy.

What are T 
Cell ?
● T Cells are a type of white blood cell 
(lymphocyte) that play a central role in the 
immune system.
● There are different types of T cells:
○ Helper T Cells: Activate other immune 
cells.
○ Cytotoxic T Cells: Directly kill infected or 
cancerous cells.
● T cells recognize foreign invaders (like cancer 
cells) through receptors on their surface.

● T Cell Therapy (or Adoptive Cell Therapy) 
What is T Cell involves extracting T cells from a patient’s body, modifying or expanding them, and then 
Therapy for reintroducing them into the patient.● The goal: To enhance the immune system's 
cancer ability to recognize and destroy cancer cells.

Types of T Cell 
Therapy
● CAR-T Cell Therapy (Chimeric Antigen Receptor T-
Cell Therapy)
○ T cells are genetically engineered to express 
a receptor specific to cancer cells.
● TCR-T Cell Therapy (T-Cell Receptor Therapy)
○ T cells are modified to target cancer-specific 
antigens presented on the surface of tumor 
cells.
● Tumor-Infiltrating Lymphocytes (TILs)
○ T cells are isolated from a patient’s tumor, 
expanded in the lab, and infused back to 
target the tumor.

Mechanism of T 
Cell Therapy
1. Extraction: T cells are collected from 
the patient's blood or tumor tissue.
2. Modification: The T cells are 
genetically modified or expanded in 
the lab.
3. Reinfusion: Modified T cells are 
reinfused back into the patient's body 
to attack cancer cells.
4. Activation: Modified T cells seek out 
and destroy tumor cells by recognizing 
cancer-specific antigens.

Risk Of T 
Cell Therapy
Allergic reactions during the infusion. 
Abnormal levels of minerals in the 
blood, such as low potassium, sodium, 
or phosphorous levels. A weakened 
immune system, with an increased risk 
of serious infections. Low blood cell 
counts, which can increase the risk of 
infections, fatigue, and bruising or 
bleeding.

Conclusion
T-cell therapy for cancer immunotherapy involves modifying a patient’s T cells to enhance 
their ability to recognize and attack cancer cells. This approach includes methods like CAR-T 
cell therapy, where T cells are engineered to target specific cancer markers. It holds promise 
as a powerful treatment option, especially for certain blood cancers, by harnessing the 
body’s immune system to fight cancer more effectively.
