Factor V Deficient Mice

Complement activation in factor D-deficient mice.

To assess the contribution of the alternative pathway in complement activation and host defense and its possible role in the regulation of systemic energy balance in vivo, factor D-deficient mice were generated by gene targeting. The mutant mice have no apparent abnormality in development and their body weights are similar to those of factor D-sufficient littermates. Complement activation could...

Characterization of tumor necrosis factor-deficient mice.

Although tumor necrosis factor (TNF) initially came to prominence because of its anti-tumor activity, most attention is now focused on its proinflammatory actions. TNF appears to play a critical role in both early and late events involved in inflammation, from localizing the noxious agent and amplifying the cellular and mediator responses at the local site and systemically, to editing (e.g., ap...

FACTOR V AND VIII INHIBITOR IN PATIENTS WITH COMBINED FACTOR V AND VIII DEFICIENCY

Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...

T cell functions in granulocyteymacrophage colony-stimulating factor deficient mice

Immunological functions were analyzed in mice lacking granulocyteymacrophage colony-stimulating factor (GM-CSF). The response of splenic T cells to alloantigens, anti-mouse CD3 mAb, interleukin 2 (IL-2), or concanavalin A was comparable in GM-CSF 1y1 and GM-CSF 2y2 mice. To investigate the responses of CD81 and CD41 T cells against exogenous antigens, mice were immunized with ovalbumin peptide ...
