Neuroimmune Pharmacology

In the past two decades, enormous strides have been made These tools for exploring brain biochemistry at the cellular in our understanding of the relationships between inflamma- level opened new vistas for understanding brain functioning tion, innate immune responses, adaptive immune responses, and the pathogenesis of human disease. Using these tools, and degenerative human diseases. The developing informa- our laboratory and that of Joseph Rogers in Sun City d- tion has mostly appeared in specialty journals that have dealt onstrated that HLA-DR was strongly expressed on activated only with isolated aspects of these tightly related fields.

The identification of HLA-DR, a well-known a result, contemporary scientists have had a difficult time leukocyte marker displayed by antigen presenting cells, on finding sources, even in review articles, that provide an these cells vindicated both Hortega and van Furth.
