High seroprevalence but short‐lived immune response to SARS‐CoV‐2 infection in Paris

Immune response to Leishmania infection.

Antileishmanial immune response is shown to be host genotype dependent so that some inbred strains of mouse are susceptible while others are resistant. The resistance is conferred by T-helper type-1 (Th1) cells while the susceptibility is conferred by Th2 cells. Th1 cells secrete IL-2 and IFN-gamma but Th2 cells secrete IL-4, IL-5 and IL-10. It has been shown that IFN-gamma activates macrophage...

Irradiated β-glucan enhances immune response to bacterial infection through CD4 and CD8 T-lymphocytes

Background: &beta-glucans are glucose polymers with a variety of stimulatory effects on the immune system. The objective of this study was to evaluate the immune-enhancing activities of low molecular weight gamma irradiated &beta-glucan (I&beta-g) extracted from Pleurotus ostreatus in response to Pseudomonas aeruginosa infection in rats. Materials and Methods: &beta-glucan (&beta-g) powder was ...

Malnutrition and impaired immune response to infection.

The cycle of events which leads to an impairment of the immune response in the malnourished child includes poverty, food deprivation and frequent infections. It is of great significance, however, that the marked suppression of the immune response can be repaired reasonably promptly, if the disease commences after the child has attained 1 year of age. Prenatal infection not only generates growt...

The immune response to surgery and infection

Surgical trauma affects both the innate and acquired immunity. The severity of immune disorders is proportional to the extent of surgical trauma and depends on a number of factors, including primarily the basic disease requiring surgical treatment (e.g. cancer), often coexisting infections and impaired nutritional status. Disorder of the immune response following surgical trauma may predispose ...
