Immune Response Signaling: Combinatorial and Dynamic Control

Immune Response Signaling: Combinatorial and Dynamic Control.

Macrophages mount complex responses to pathogens. Although several key signaling pathways have been identified, it remains unclear how they work together to provide specificity. In a recent paper, Gottschalk et al. report that differential dose-response behaviors of the NFκB and MAPK pathways allow dose-specific gene expression programs.

Signaling in the immune response.

Many pathogens that can infect C. elegans have been described, including some that co-exist with the nematode in its natural environment. This chapter describes our current understanding of the different innate immune responses of C. elegans that follow infection. It focuses on the main signalling pathways that have been identified and highlights the inclusion of certain molecular cassettes in ...

Dynamic Metabolism in Immune Response

Cell, the basic unit of life depends for its survival on nutrients and thereby energy to perform its physiological function. Cells of lymphoid and myeloid origin are key in evoking an immune response against "self" or "non-self" antigens. The thymus derived lymphoid cells called T cells are a heterogenous group with distinct phenotypic and molecular signatures that have been shown to respond ag...

Modulating the innate immune response by combinatorial engineering of endotoxin.

Despite its highly inflammatory nature, LPS is a molecule with remarkable therapeutic potential. Lipid A is a glycolipid that serves as the hydrophobic anchor of LPS and constitutes a potent ligand of the Toll-like receptor (TLR)4/myeloid differentiation factor 2 receptor of the innate immune system. A less toxic mixture of monophosphorylated lipid A species (MPL) recently became the first new ...
