Which of te following is released initially as an inflammatory response ?

Options

A. Interferon
B. Chitin
C. Cytokines
D. Cytokinin

Answer

To answer the question "Which of the following is released initially as an inflammatory response?", we will analyze the given options step by step.

### Step 1: Understand the options
The options provided are:
1. Interferons
2. Chitin
3. Cytokines
4. Cytokinins

### Step 2: Analyze each option

**Option 1: Interferons**
- Interferons are proteins secreted by virus-infected host cells.
- Their primary role is to protect neighboring non-infected cells from viral infection.
- They are not involved in the initial inflammatory response.
- **Conclusion:** Incorrect option.

**Option 2: Chitin**
- Chitin is a polysaccharide found in the cell walls of fungi.
- It does not play a role in the immune response or inflammatory response.
- **Conclusion:** Incorrect option.

**Option 3: Cytokines**
- Cytokines are signaling proteins that play a crucial role in the immune system.
- They are released during the inflammatory response, particularly pro-inflammatory cytokines.
- Examples include Interleukin-1 (IL-1), Interleukin-6 (IL-6), and Tumor Necrosis Factor-alpha (TNF-alpha).
- **Conclusion:** Correct option.

**Option 4: Cytokinins**
- Cytokinins are plant hormones involved in cell division and growth in plants.
- They have no relevance to the immune or inflammatory response in animals.
- **Conclusion:** Incorrect option.

### Step 3: Final Answer
Based on the analysis, the correct answer is **Cytokines**, as they are released initially during the inflammatory response.
