Question

Match the LIST-I with LIST-II

• A. A-IV, B-II, C-I, D-III
• B. A-III, B-IV, C-II, D-I
• C. A-IV, B-III, C-I, D-II
• D. A-II, B-III, C-I, D-IV

Hint:

Immune Cell Key Matches:
Neutrophils = Acute Inflammation.
NK Cells = CD16 Receptors (ADCC).
Lymphocytes = T and B Cells.
Eosinophils = Helminthic Parasitic infections.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks to match immune cell types in LIST-I with their characteristic cell surface markers, functiol responses, or categories in LIST-II.

Step 2: Key Formula or Approach:
Match immune cells with their immunological functions:
• Neutrophils: Primary phagocytic cells recruited rapidly during acute inflammation.

• tural Killer (NK) cells: Express CD16 (Fc$\gamma$RIII) receptors to mediate ADCC.

• Lymphocytes: Subdivided into adaptive T cells and B cells.

• Eosinophils: Specialized granulocytes providing defense against parasitic helminths.

Step 3: Detailed Explation:

• A. Neutrophils $\to$ IV. Inflammation: Neutrophils are the most abundant circulating leukocytes and act as first responders during acute inflammatory responses.

• B. tural killer cells $\to$ III. CD16 receptors: NK cells express CD16 (Fc$\gamma$RIII) and CD56 surface receptors, using CD16 to bind antibody-coated target cells for ADCC.

• C. Lymphocytes $\to$ I. T and B cells: Lymphocytes represent agranulocytes that comprise T cells (cell-mediated) and B cells (humoral immunity).

• D. Eosinophils $\to$ II. Parasitic organism: Eosinophils release major basic protein (MBP) and eosinophil cationic protein to destroy large extracellular parasites like helminths.

Step 4: Fil Answer:
The correct matching sequence is A-IV, B-III, C-I, D-II.
