Differences in innate immune response between man and mouse

Differences in innate immune response between man and mouse.

Mouse strains are frequently used to model human disease states, to test the efficiency of drugs and therapeutic principles. However, the direct translation of murine experimental data to human pathological events often fails due to sufficient differences in the organization of the immune system of both species. Here we give a short overview of the principle differences between mice and humans ...

Mouse strain-dependent differences in susceptibility to Neisseria gonorrhoeae infection and induction of innate immune responses.

Acute gonorrhea in women is characterized by a mucopurulent exudate that contains polymorphonuclear leukocytes (PMNs) with intracellular gonococci. Asymptomatic infections are also common. Information on the innate response to Neisseria gonorrhoeae in women is limited to studies with cultured cells, isolated immune cells, and analyses of cervicovaginal fluids. 17beta-Estradiol-treated BALB/c mi...

Induction of Innate Immune Response

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...

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...
