Lymphocyte transformation, interferon, and leukocyte migration inhibition factor synthesis were studied in purified lymphocyte cultures for 20 children with congenital rubella and 18 healthy children (seven susceptible and 11 immune to rubella). Lymphocyte transformation after phytohemagglutinin stimulation was significantly lower in children with congenital rubella as compared to healthy controls. Responses to purified rubella virus were absent in the susceptible controls and absent or at least two times lower in congenital rubella children than in immune controls. After purified rubella virus stimulation, leukocyte migration inhibition factor production was detected in all immune controls, but in none of the susceptible controls, or the congenital rubella-infected children. The results varied with gestational age of intrauterine infection: the impairment of cellular immune response, both after phytohemagglutinin or rubella virus stimulation, was more severe in the children infected in the first two months than in the latter stages of gestation.

CD11d/CD18 is the most recently discovered and least understood β2 integrin. Known CD11d adhesive mechanisms contribute to both extravasation and mesenchymal migration – two key aspects for localizing peripheral leukocytes to sites of inflammation. Differential expression of CD11d induces differences in monocyte/macrophage mesenchymal migration including impacts on macrophage sub-set migration. The participation of CD11d/CD18 in leukocyte localization during atherosclerosis and following neurotrauma has sparked interest in the development of CD11d-targeted therapeutic agents. Whereas the adhesive properties of CD11d have undergone investigation, the signalling pathways induced by ligand binding remain largely undefined. Underlining each adhesive and signalling function, CD11d is under unique transcriptional control and expressed on a sub-set of predominately tissue-differentiated innate leukocytes. The following review is the first to capture the nearly three decades of CD11d research and discusses the emerging role of CD11d in leukocyte migration and retention during the progression of a staged immune response.
