Which option incorrectly matches a cell adhesion receptor to its location?

Which option incorrectly matches a cell adhesion receptor to its location?

• A. E cadherins in epithelial cells
• B. P cadherins in placenta
• C. N cadherins in neural tissue
• D. L cadherins in muscle tissue

Answer: (D)

L cadherins are primarily found in the central nervous system and have roles in processes such as neuronal development, rather than being associated with muscle tissue. This misalignment of L cadherin with muscle tissue makes the pairing incorrect. E cadherins are indeed found in epithelial cells, providing strong intercellular adhesion; P cadherins are associated with placental tissues, contributing to the adhesion of trophoblast cells in the placenta; and N cadherins play a critical role in the development and connectivity of neural tissues, facilitating cell adhesion during neural tissue formation. Thus, D is the only pairing that does not accurately describe the correct location of the cell adhesion receptor.
