Schistosoma mansoni: evidence that immunity in vaccinated and chronically infected CBA/Ca mice is sensitive to treatment with a monoclonal antibody that depletes cutaneous effector cells

Abstract

Naive mice, mice vaccinated 4 weeks previously with radiation-attenuated cercariae of Schistosoma mansoni and mice infected 16 weeks previously with normal S. mansoni cercariae were treated with a rat monoclonal antibody (NIMP-R14), that has been reported elsewhere to recognize neutrophils selectively. The establishment of a primary schistosome population in naive mice was not affected by the administration of this reagent. In contrast, immune-dependent challenge elimination was reduced in both vaccinated and chronically infected mice following treatment with NIMP-R14. Maximal suppression of resistance in both vaccinated (67% mean reduction) and chronically infected (44% mean reduction) mice was achieved when NIMP-R14 was injected intraperitoneally on the day of challenge. The monoclonal was markedly less effective when administered on or after day 3. Analysis of the blood leucocyte profiles of vaccinated/NIMP-R14 treated mice showed that the monoclonal totally abrogated neutrophils from the peripheral circulation between days 1 and 6. Histological examination of the skin site of challenge revealed, however, that NIMP-R14 treatment had reduced the number of eosinophils and macrophages as well as neutrophils in the cutaneous tis...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.
