Question

List the 7 molecules (receptors, signalers and excreted molecules) that come from a mature dendritic cell

Answer 1

A mature dendritic cell releases cytokines, chemokines, MHC molecules, and costimulatory molecules to coordinate immune responses.

Step-by-step explanation:

A mature dendritic cell releases several molecules:

1. Cytokines: such as interferon, interleukin, and tumor necrosis factor, which help regulate immune responses.
2. Chemokines: such as CCL19 and CCL21, which attract immune cells to the site of infection.
3. Major Histocompatibility Complex (MHC) molecules: present antigenic peptides to T cells.
4. Costimulatory molecules: like CD80 and CD86, which help activate T cells.

These molecules allow the dendritic cell to communicate with other immune cells and coordinate an effective immune response. By presenting antigens and secreting signaling molecules, a mature dendritic cell plays a crucial role in initiating and regulating immune responses.
