The correct Answer is:
To solve the question "CD4 complex is found on," we can follow these steps: ### Step-by-Step Solution: 1. **Understand the CD4 Complex**: - CD4 stands for "Cluster of Differentiation 4." It is a glycoprotein found on the surface of certain immune cells. 2. **Identify the Function of CD4**: - CD4 serves as a co-receptor for the T cell receptor (TCR) on T cells. This means it plays a crucial role in the immune response by helping T cells recognize antigens. 3. **Determine Where CD4 is Found**: - CD4 is primarily found on the surface of helper T cells (also known as CD4+ T cells). It is also present on other immune cells like monocytes, macrophages, and dendritic cells. 4. **Analyze the Options Given**: - The options provided are: 1. Helper T cells 2. Killer T cells 3. Cytotoxic T cells 4. Both 1 & 3 - From our understanding, CD4 is specifically associated with helper T cells. 5. **Select the Correct Answer**: - Since CD4 is primarily found on helper T cells, the correct answer is **Helper T cells**. ### Final Answer: - The CD4 complex is found on **Helper T cells**.
