Immunology

Step 1: Understanding the Concept: Modern cancer treatment often involves immunotherapy, which utilizes specific substances called biological response modifiers to enhance the body's natural defense mechanisms against tumors.
Step 2: Key Formula or Approach: Identify the therapeutic agent used clinically to boost the immune response against cancer cells among the given biological molecules.
Step 3: Detailed Explanation: Tumor cells frequently exhibit sophisticated mechanisms to evade detection and destruction by the host's immune system.
To counteract this evasion, cancer patients are administered biological response modifiers.
-Interferon is a classic clinical example of such a modifier.
When administered, -Interferon rapidly activates the patient's immune system, specifically enhancing the activity of natural killer (NK) cells and cytotoxic T-cells, which in turn helps in recognizing and aggressively destroying the tumor cells.
Histamine and Serotonin are general inflammatory mediators and neurotransmitters, not specific anti-tumor agents.
-Lactalbumin is a simple nutritional protein found in milk.
Step 4: Final Answer: The correct option is (2).
