Beschreibung:
Immunoglobulin G (IgG) responses require major histocompatibility complex (MHC)-restricted recognition of peptide fragments by conventional CD4(+) helper T cells. Immunoglobulin G responses to glycosylphosphatidylinositol (GPI)- anchored protein antigens, however, were found to be regulated in part through CD1d-restricted recognition of the GPI moiety by thymus-dependent, interleukin-4-producing CD4(+), natural killer cell antigen 1.1 [(NK1.1)+] helper T cells. The CD1-NKT cell pathway regulated immunogobulin G responses to the GPI-anchored surface antigens of Plasmodium and Trypanosoma and may be a general mechanism for rapid, MHC-unrestricted antibody responses to diverse pathogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schofield, L -- McConville, M J -- Hansen, D -- Campbell, A S -- Fraser-Reid, B -- Grusby, M J -- Tachado, S D -- AI-40171/AI/NIAID NIH HHS/ -- GM 41071/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jan 8;283(5399):225-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Walter and Eliza Hall Institute of Medical Research, Post Office, Royal Melbourne Hospital, Victoria 3050, Australia. schofield@wehi.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9880256" target="_blank"〉PubMed〈/a〉
