The effects of antigen on the migration of recirculating lymphocytes through single lymph nodes.

摘要: The increased input of RL into LN starts within 3 h after antigenic stimulation and is due to an increase in the number passing through a LN. It not associated with altered transit time majority it cannot occur absence high endothelial PCV. immediate decrease output from antigen-stimulated delay exit that which had entered before antigen was given. cell administration affects blast cells produced as well small lymphocytes specific for RL. There are at least two distinct mechanisms controlling migration first controls occurs only second output, although does level PCV, can organized lymphoid tissue. decreased independently possibly controlled by different mechanisms.
