Explanation:
Detailed explanation-1: -The intercellular junctions of epithelial cells are of four types (Figures 1.1 and 1.2). There are two types of adhesive or adherens junctions, firstly desmosomes or maculae adherentes, and secondly the so-called intermediate junctions, often zonular in structure, the zonulae adherentes.
Detailed explanation-2: -Claudins are tight junction membrane proteins that are expressed in epithelia and endothelia and form paracellular barriers and pores that determine tight junction permeability.
