Researchers have uncovered a unique ability of a special subtype of natural killer cells in the immune system, called adaptive NK cells, to remember ovarian tumors and effectively attack them. The discovery could pave the way for new, more powerful immunotherapies for difficult-to-treat cancers.

Researchers show that the immune system can recognize and control the latent stage of the parasite Toxoplasma gondii, a finding that can inform the study of latency in other infections of the nervous system.

A new study suggests a nasal spray developed to target neuroinflammation could one day be an effective treatment for traumatic brain injury (TBI). By studying the effects of the nasal anti-CD3 in a mouse model of TBI, researchers found the spray could reduce damage to the central nervous system and behavioral deficits, suggesting a potential therapeutic approach for TBI and other acute forms of brain injury.

Ingwer ist besonders in der kalten Jahreszeit ein beliebtes Hausmittel, vor allem bei Erkältungen. Viele schwören auf die gesundheitsfördernde Knolle, doch wie lässt sie sich am besten aufbewahren, damit sie lange frisch bleibt?

Prolonged illnesses like cancer and chronic infections often leave the immune system in a state of exhaustion, where its frontline defenders -- T cells -- lose their ability to function effectively. Researchers have identified a rare type of immune cells, called stem-like T cells, that holds the key to maintaining powerful, long-term immune responses.

Researchers have shown that people 60 years or older with weakened immunity do not respond as strongly to vaccines against the respiratory syncytial virus (RSV) as people in the same age group with normal immune function.

Fieber ist bei Infektionen eine sinnvolle Reaktion des Körpers. Aber es kann auch lebensgefährlich werden. Wie gesund Fieber ist, welche Ursachen es hat, was Sie bei Fieber mit Hausmitteln selbst tun können und wann der Arzt gefragt ist.Von FOCUS-online-Autorin Monika Preuk

Effective immunity hinges on the ability to sense infection and cellular transformation. In humans, there is a specialized molecule on the surface of cells termed MR1. MR1 allows sensing of certain small molecule metabolites derived from cellular and microbial sources; however, the breadth of metabolite sensing is unclear. Researchers have identified a form of vitamin B6 bound to MR1 as a means of engaging tumor-reactive immune cells.

Ein chronisch entzündeter Darm zermürbt und belastet enorm. Doch die jüngste Forschung weckt in Patienten vorsichtige Hoffnung auf Heilung – sei es per Genreparatur oder mit Wurmeiern. Von FOCUS-online-Autorin Petra Apfel
