Question

Which of the cell junctions is involved in creating a barrier between cells?

Answer 1

Tight junctions are cell junctions that seal tissues. These junctions form protective and functional barriers.

• The cell junction that is involved in creating a barrier between cells is the TIGHT junction.

• The tight junctions are cell-cell adhesion structures implicated in cell polarity and signaling.

• On the other hand, adherens junctions are cell junctions required for maintaining contact inhibition.

• Finally, desmosomes are intercellular junctions that bind intermediate filaments of the cytoskeleton with cadherin proteins.
