Leukocyte extravasation | leukocyte adhesion and rolling

This lecture explains about the leukocyte extravasation process step by step. Leukocytes start migrating towards the released chemokines from the damaged and infected tissues and it has the leukocyte rolling through the blood vessels with the help of selectin protein. Then with the help of integrin, leukocytes stick to and adhere to the blood vessel wall. Then it can squeeze through the blood vessel wall towards the chemical molecules and start to initiate the cell mediated immune response. This whole process is known as the leukocyte extravasation.
