The heat and chills that come with fever are not only uncomfortable but also metabolically costly. Increased body temperature, however, can make all the difference when you’re sick.
Los científicos muestran cómo las células inmunitarias migran a lo largo de gradientes autogenerados 05.09.2023 – Austria Cuando luchan contra una enfermedad, nuestras células inmunitarias necesitan llegar rápidamente a su objetivo. Investigadores del Instituto de Ciencia y Tecnología de Austria (ISTA) han descubierto ahora que las células inmunitarias generan activamente su propio sistema de guía para navegar … Read more
Mientras que los enfoques convencionales suelen clasificar los trastornos del sistema inmunológico según regiones específicas del cuerpo y, por tanto, se contemplan de forma aislada, un enfoque sistémico pretende ofrecer una imagen más detallada de los mecanismos subyacentes, permitiendo una mejor predicción de terapias. 04/09/2023 Los enfoques basados en redes revelan, a menudo,aquello que … Read more
How are people with long COVID faring two years after their initial infection? Many have recovered. Some still struggle with symptoms – this is more likely for those who were initially hospitalised.
Cómo afecta al sistema inmunitario de los astronautas estar en el espacio Un nuevo estudio dirigido por investigadores del Instituto Karolinska de Suecia ha examinado cómo las células T del sistema inmunitario se ven afectadas por la ingravidez. Los resultados, publicados en la revista ‘Science Advances’, podrían explicar por qué las células T de los … Read more
by Sarah C.P. Williams, Gladstone Institutes Gamma delta T cells, a special type of cell in the immune system, are incredibly effective at recognizing and killing cancer cells. Cancer patients with higher levels of these T cells in their tumors tend to fare better than those with lower levels. But scientists have struggled to understand exactly … Read more
by Duke University Medical Center A man-made antibody successfully prevented organ rejection when tested in primates that had undergone a kidney transplant, Duke Health researchers report. The finding clears the way for the new monoclonal antibody to move forward in human clinical trials. Results of the study appear online Aug. 30 in the journal Science Translational Medicine. … Read more
by University of California – San Diego Our immune system has an ingenious trick up its sleeve. It remembers past foes, stopping potential sickness in its tracks through a phenomenon known as immunological memory. This is thanks to specialized cells—tissue-resident memory T cells—which reside in vital organs like the small intestine, lungs and other areas. Consider … Read more
T cells recognize and kill cancer cells but quickly lose their effectiveness. This fast dysfunction may help explain why immunotherapy doesn’t lead to long-term remission for many patients.
We know from other viruses that viral fragments can remain in different tissues for months or even years. This could be the case for long COVID.
