The promised land of human immunology

Advances in technology and data analysis have made it possible to take a new look at human immunology. These advances run the gamut from systems biology approaches, which are likely in the vanguard of how we can start "to put the pieces together" of immune function, to a deeper understanding of specific diseases and vaccines and the immune repertoire. In our own experience, we have also found that asking simple questions about human immunity has often given us very surprising answers, causing a rethink of established dogma. Thus, we have developed a new perspective on the nature of the αβ TCR repertoire and also the likely role of T-cell repertoire (TCR) cross-reactivity in generating T memory independent of specific antigen interactions. These findings show that human immunology is not just a necessary step for "translating" basic immunology to treat diseases or develop better vaccines, but is also an important complement to the inbred mouse model.
