Question

Antigen-presenting cells communicate with effector cells of the immune system. Select the correct statement.

• A. Direct cell membrane- to- membrane contact
• B. Quorum sensing
• C. Release of highly specific steroidal hormones
• D. Release of neurotransmitter-like substances
• E. Induction of rapid ion flow through the membrane

Answer 1

The correct option is A Direct cell membrane- to- membrane contact

Answer is option A i.e. "Direct cell membrane- to- membrane contact"
Antigen-presenting cells (APC) are immune system cells that present antigens on the cell surface which then communicate with appropriate T cell receptors by membrane-to-membrane contact. Antigen-presenting cells are involved in both the innate and adaptive immune responses.
