Mathematical models for immunology:current state of the art and future research directions
The advances in genetics and biochemistry that have taken place over the last 10 years led to significant advances in experimental and clinical immunology. In turn, this has led to the development of new mathematical models to investigate qualitatively and quantitatively various open questions in immunology. In this study we present a review of some research areas in mathematical immunology that evolved over the last 10 years. To this end, we take a step-by-step approach in discussing a range of models derived to study the dynamics of both the innate and immune responses at the molecular, cellular and tissue scales. To emphasise the use of mathematics in modelling in this area, we also review some of the mathematical tools used to investigate these models. Finally, we discuss some future trends in both experimental immunology and mathematical immunology for the upcoming years

Cell-secreted Gp96-Ig-peptide complexes induce lamina propria and intraepithelial CD8+ cytotoxic T lymphocytes in the intestinal mucosa
Induction of mucosal immunity is critical for protection from enteric pathogens. Heat shock protein gp96 is one of the primary peptide and protein chaperones located in the endoplasmic reticulum. We reported previously that a cell-secreted gp96-Ig fusion protein (gp96-Ig) mediated strong systemic, antigen-specific CD8-CTL expansion in vivo. We now evaluate the mucosal immune response to stimulation by secreted gp96 using allogeneic NIH-3T3 transfected with ovalbumin (OVA) and gp96-Ig. A single intraperitoneal NIH-3T3-OVA-gp96-Ig immunization caused significant homing of OVA-specific TCR transgenic CD8 cells (OT-I) to Peyer's patches, to the intraepithelial compartment and to the lamina propria. Intraperitoneal immunization with cells secreting gp96-Ig provided stronger mucosal immunity than the same dose instilled vaginally or rectally or injected subcutaneously or intradermally. Our results provide the first evidence that cell-based gp96-Ig-secreting vaccines may serve as a potent modality to induce mucosal immunity
