Induction of Innate Immune Response

Cyclic Dinucleotides and the Innate Immune Response

Cyclic dinucleotides (CDNs) have been previously recognized as important secondary signaling molecules in bacteria and, more recently, in mammalian cells. In the former case, they represent secondary messengers affecting numerous responses of the prokaryotic cell, whereas in the latter, they act as agonists of the innate immune response. Remarkable new discoveries have linked these two patterns...

Rotavirus Antagonism of the Innate Immune Response

Rotavirus is a primary cause of severe dehydrating gastroenteritis in infants and young children. The virus is sensitive to the antiviral effects triggered by the interferon (IFN)-signaling pathway, an important component of the host cell innate immune response. To counteract these effects, rotavirus encodes a nonstructural protein (NSP1) that induces the degradation of proteins involved in reg...

Optimal control of innate immune response

Treatment of a pathogenic disease process is interpreted as the optimal control of a dynamic system. Evolution of the disease is characterized by a non-linear, fourth-order ordinary differential equation that describes concentrations of pathogens, plasma cells, and antibodies, as well as a numerical indication of patient health. Without control, the dynamic model evidences sub-clinical or clini...

Neutrophils in the innate immune response.

Polymorphonuclear leukocytes (PMNs or neutrophils) are an essential component of the human innate immune system. Circulating neutrophils are rapidly recruited to sites of infection by host- and/or pathogen-derived components, which also prime these host cells for enhanced microbicidal activity. PMNs bind and ingest microorganisms by a process known as phagocytosis, which typically triggers prod...
