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.
Se trata del estudio que describe la aplicación de un método inmunológico clásico pero con una aplicación novedosa adaptada al COVID para valorar la respuesta inmunitaria celular en población con vacunas mRNA La Dra. Yvelise Barrios agradeció este reconocimiento y recogió el premio de manos del Dr. Francisco Perera. El premio lleva consigo el nombramiento … Read more
Cancer vaccines are an emerging personalised treatment for cancer. Using the same mRNA technology as COVID vaccines, they stimulate the immune system to destroy cancer cells.
El hallazgo abre la vía al uso de inhibidores de la interleucina-22 para prevenir la diseminación de la enfermedad. Un equipo científico internacional ha determinado que la interleucina (IL)-22 producida por los linfocitos T promueve las metástasis, actuando sobre el receptor de esta citoquina (IL-22RA1) en el tumor primario. Como consecuencia de esta interacción el … Read more
Why are Australian black swans so quick to die from bird flu? A new genome study comparing them to their bird brethren helps to unravel the mystery.
