Researchers at the Institut Pasteur and the Institut Cochin have demonstrated the presence of an immune memory in certain white blood cells that remain in the bladder. (pasteur.fr)
We found that certain white blood cells, known as memory T cells, appear during an initial infection. (pasteur.fr)
These are called 'resident' cells because they develop in the bladder during infection and then stay there to fight subsequent infections," explains Matthieu Rousseau, a unit researcher and first author of the study. (pasteur.fr)
NIAID-supported researchers have found evidence that although HIV infection may adversely affect the thymus, the gland continues to produce new T cells after the infection is suppressed by intensive anti-HIV therapy. (sciencedaily.com)
Immune cells that lose function and become exhausted during chronic infections develop long-term "scars" in regulatory elements of the genome and do not fully recover after the virus is cleared. (massgeneral.org)
Treatments that target these scarred regions or regulatory molecules expressed by the immune cells might help restore the cells' function. (massgeneral.org)
These scars might be locking the exhausted T cells and preventing return to proper function even if the chronic infection in the patient is cured," notes Sen. "Thus, restoring the function of these cells will likely require directly removing or inactivating these scarred regions to unlock the cells' functionality. (massgeneral.org)
Fighting off infections depends largely on our bodies' capacity to quickly recognize infected cells and destroy them, a job carried out by a class of immune cells known as CD8 + T cells. (futurity.org)
In most cases, CD8 + T cells quickly recognize and destroy infected cells to prevent the infection from spreading. (futurity.org)
Importantly, this pathway can be targeted to restore some functionality to the T cells and enhance the capacity to control infection. (futurity.org)
Here we describe a novel assay for monitoring prion uptake and trafficking by immune cells immediately following intraperitoneal inoculation by purifying and fluorescently labeling aggregated prion rods from infected brain material then monitoring their uptake and movement from the injection site and characterizing the cells mediating these events.

We designed a multicenter study to evaluate the efficacy of intravenous immune globulin in children with advanced HIV infection who were receiving zidovudine. (soton.ac.uk)
METHODS: In a double-blind trial 255 children between 3 months and 12 years of age who had the acquired immunodeficiency syndrome (AIDS) or AIDS-related complex were randomly assigned to receive either intravenous immune globulin (400 mg per kilogram of body weight) (n = 129) or placebo (0.1 percent albumin) (n = 126) every 28 days. (soton.ac.uk)
The two-year survival was similar in the two groups: 79.2 percent among immune globulin recipients and 75.4 percent among placebo recipients (P = 0.41). (soton.ac.uk)

To explore potential correlates of protection, a suite of 29 immune parameters were assessed in the mice at the end of the experimental period. (nih.gov)
Similarly, mice can be re-infected with the same strain of Bb, implying a lack of functional immune responses. (canlyme.com)
However, induction of all other immune parameters was normal and both T1-deficient and T1-Fc-transgenic mice were able to clear the parasite infection within 12 days with kinetics similar to those in control mice. (gla.ac.uk)

As the pathogenesis of viral illnesses is affected by host immune responses, various immune modulators have been proposed as biomarkers to predict the risk of the disease progression to a severe form, at a much earlier stage of the illness. (frontiersin.org)
When I started my career as a nurse practitioner in 2017, I couldn't have guessed that I'd end up where I am today - a psychiatric provider treating children, adolescents, and adults with a largely misunderstood and relatively controversial diagnosis that causes severe neuropsychiatric symptoms due to a misdirected immune response. (lindnercenterofhope.org)
When we tracked temporal changes in parasite VSA expression to ask whether variants associated with severe disease preferentially expand in naive hosts (as predicted by current theory) we found that var gene profiles were unchanged after 10-days of infection. (medrxiv.org)
The team also found a higher level of HLA-DR low monocytes in infants with severe RSV infections, which was unique to that subgroup. (contagionlive.com)
Theses findings are especially helpful in understanding more severe disease predispositions and what might indicate if a patient is likely to require hospitalization or have severe infection. (contagionlive.com)
As RSV is a frequent infection in children and infants, there is a continued need for more studies to understand RSV and the pathophysiology that results in more severe illness and even morbidity. (contagionlive.com)
