Energetic and nutritional regulation of the adaptive immune response and trade-offs in ecological immunology

Article Abstract:

The interest in ecological immunology can be understood by an understanding of the mechanisms involved in generating and maintaining a functional, protective immune response. This would help in the development of more biologically accurate concepts of fitness costs involved in generating such responses.
