Brug af psilocybin skal man være forsigtig med, siger forskere, der har undersøgt næsten 2000 mennesker, som siger, at de har haft negative erfaringer efter at have taget psilocybin-holdige svampe.

En af hovedårsagerne til at kræft er vanskeligt at behandle er, at kræftceller har udviklet talrige mekanismer, som gør det muligt for dem at undgå at blive nedbrudt af immunsystemet. En af disse mekanismer omfatter MDSC-celler, nemlig myeloid-afledte hæmmerceller (myeloid-derived suppressor cells). Ny forskning har givet ny indsigt i, hvordan MDSC-celler gør det muligt for kræftceller at omgå immunangreb.
Latest Science News -- ScienceDaily100+
Role for immune cells in cancer’s ability to evade immunotherapyOne of the main reasons cancer remains difficult to treat is that cancer cells have developed a multitude of mechanisms that allow them to evade destruction by the immune system. One of these escape mechanisms involves a type of immune cell called myeloid-derived suppressor cells (MDSCs). A recent study provides new insight into how MDSCs enable tumor cells to circumvent immune attack and offer th
