Investigation of hCAR2 antagonists as a potential strategy to modulate bovine leukocytes

Background Dairy cows experiencing ketosis after calving suffer greater disease incidence and are at greater risk of leaving the herd. In vitro administration of beta-hydroxybutyric acid(BhBA;the primary blood ketone) has inhibitory effects on the function of bovine leukocytes. BhBA is a ligand of hCAR2 and the activation of these receptors promotes an anti-inflammatory response which may be related with immunosuppression observed in transition dairy cattle. The objective of this study was to identify and test antagonists for hCAR2 in bovine immune cells cultured with *** We observed expression of hCAR2 at the protein level within lymphocytes, monocytes, and granulocytes. The proportion of cells expressing hCAR2 tended to be greater in mid-lactation compared to early lactation cows;the increase was a result of increased proportion of T and B cells expressing hCAR2. Stimulation of hCAR2 with niacin or BhBA promoted Ca^(2+) mobilization in neutrophils and mononuclear cells. Mononuclear cells treated with BhBA had diminished intracellular Ca^(2+) responses when hCAR2 was knocked down by si RNA silencing, indicating Ca^(2+) mobilization was mediated by hCAR2 signaling. Two candidate antagonists for hCAR2, synthesized from niacin(NA-1 and NA-5), were tested;monocytes and neutrophils pre-treated with NA-1 and NA-5 had reduced Ca^(2+) mobilization after incubation with BhBA. Furthermore, NA-5 but not NA-1 prevented BhBA-associated reductions in cyclic *** We demonstrated that hCAR2 is present on bovine leukocytes and has greater expression later in lactation. We confirmed that BhBA and niacin derived hCAR2 antagonists alter bovine leukocyte activity. Our results demonstrate that both BhBA and niacin affect bovine leukocyte Ca^(2+) mobilization in a hCAR2-dependent manner.

Analysis of ancient mass extinction recoveries in marine environments: generating strategies for managing outcomes of the current mass extinction

引用

National Science Review 2024年第1期11卷 8-10页

作者： David j.Bottjer Department of Earth Sciences University of Southern California

The defining feature of a mass extinction and its associated recovery is the global amount of extinction that occurred[1]. however, there is finer-scale detail to the story, as seen in the ongoing modern mass extinction(the sixth mass extinction), which exhibits variable effects among marine ecosystems and environments, and hence geographic areas [1].

Global weirding at mass extinction horizons

引用

National Science Review 2024年第1期11卷 10-12页

作者： Gregory j.Retallack Department of Earth Sciences University of Oregon

A strong motivation for studying mass extinctions is understanding how current climatic and biodiversity crises will affect creatures living on land such as ourselves. Perhaps the question is: how bad can it get? In that case, terrestrial Permian-Triassic mass extinctions are an irresistible worst-case scenario [1].
