Multiple Choice

Why are adhesion molecules considered a form of cell communication in immune responses?

Adhesion molecules allow immune cells to attach to infected cells & signal immune responses.

Adhesion molecules allow immune cells to attach to endothelial cells & trigger immune cell entry into tissues.

Adhesion molecules act as channels that allow signals to travel between two neighboring cells.

Adhesion molecules are signals sent from immune cells to infected cells to trigger apoptosis.

A and B.

Verified step by step guidance

Understand the role of adhesion molecules in the immune system. Adhesion molecules are proteins located on the cell surface that facilitate the binding of cells to each other or to the extracellular matrix.

Explore how adhesion molecules contribute to immune responses. They are crucial for the attachment of immune cells to infected or target cells, allowing for direct communication and signaling.

Examine the process of immune cell migration. Adhesion molecules enable immune cells to adhere to endothelial cells, which line blood vessels, facilitating their movement into tissues where they are needed.

Consider the signaling function of adhesion molecules. While they primarily facilitate physical attachment, this interaction can also trigger signaling pathways that activate immune responses.

Evaluate the options given in the problem. Options A and B describe the roles of adhesion molecules in immune cell attachment and migration, which are key aspects of cell communication in immune responses.
