Indeed, IP agonists are used to treat patients pathological vasoconstriction diseases. [16] The injection of IP activators into the skin of rodents increases local capillary permeability and swelling; IP(-/-) mice fail to show this increased capillary permeability and swelling in response not only to IP activators but also in a model of ...
Intraperitoneal injection or IP injection is the injection of a substance into the peritoneum (body cavity). It is more often applied to non-human animals than to humans. In general, it is preferred when large amounts of blood replacement fluids are needed or when low blood pressure or other problems prevent the use of a suitable blood vessel for intravenous injection.
Nude mice were the earliest immunodeficient mouse model. These mice primarily produced IgM and had minimal or no IgA. As a result, they did not exhibit a rejection response to allogeneic tissue. Commonly utilized strains included BALB/c-nu, Swiss-nu, NC-nu, and NIH-nu, which were extensively employed in the research of immune diseases and tumors.
Hydrodynamic Delivery (HD) is a method of DNA insertion in rodent models. Genes are delivered via injection into the bloodstream of the animal, and are expressed in the liver. This protocol is helpful to determine gene function, regulate gene expression, and develop pharmaceuticals in vivo. [1] W. Heston giving an intravenous injection to mice.
BLT2 receptor knockout mice exhibit attenuated ovalbumen-induced allergic airway eosinophilia and interleukin 13 (IL-13) content in their bronchoalveolar lavage fluid compared with wild type mice and CD4-positive T cells isolated from the knockout mice showed a reduction IL-13 production but there was no change in the bronchospasm response to ...
Mice differ from humans in several immune properties: mice are more resistant to some toxins than humans; have a lower total neutrophil fraction in the blood, a lower neutrophil enzymatic capacity, lower activity of the complement system, and a different set of pentraxins involved in the inflammatory process; and lack genes for important ...
These ICV injections result in models for the sporadic Alzheimer's disease (sAD) form, rather than familial. A characteristic of sAD is an insulin-resistant brain state (IRBS). Streptozotocin is a beta-cytotoxic drug and by injecting it directly into the cerebral ventricles, the treated mice develop symptoms that align with sAD symptoms in humans.
A single ip injection (in inducible fetal lung supernatants) of 100 mg/kg of 3-MC to the mothers resulted in a maximal 50-fold induction of AHH activity by 8 hr, which persisted for 48 hr. The same injections to adult F1 mice revealed only a 4- to 7—fold increase in lung AHH activity, compared to the large fetal induction ratio. [19]
