Deficiency of leukocyte-specific protein 1 (LSP1) alleviates asthmatic inflammation in a mouse model.

Background: Asthma is a major cause of morbidity and mortality in humans. The mechanisms of asthma are still not fully understood. Leukocyte-specific protein-1 (LSP-1) regulates neutrophil migration during acute lung inflammation.

Hyperprolactinemia Impaired the Effects of Lipopolysaccharide on Both Body Temperature and Sickness Behavior in Virgin Female Rats.

Objective: Previously we observed an attenuation of body temperature in lactating rats treated with lipopolysaccharide (LPS) compared with virgin saline-treated females. We proposed that high levels of prolactin (PRL) during lactation may induce this attenuation because PRL has a suppressive effect on inflammation. In the present study, we induced hyperprolactinemia in female virgin rats to investigate the effects of PRL on body temperature and sickness behavior induced by LPS.
