Cancer-fighting immune cells in patients with lung cancer whose tumors do not respond to immunotherapies appear to be running on a different “program” that...
by Walter and Eliza Hall Institute WEHI researcher Dr Michael Chopin have made a surprise discovery about how immune ‘sentinel’ cells are maintained, which could have implications for drugs in development for treating cancer.

by Ludwig Maximilian University of Munich Immunfluorescence of mononuclear phagocytes in the murine kidney. Credit: Barbara Schraml, Stephan Rambichler; LMU The immune system is highly complex. For example, a particular class of cells called mononuclear phagocytes (MNPs) plays important roles in the uptake and disposal of damaged cells, the elimination of invasive pathogens and other foreign...

Credit: Ye Ouyang / University of Wuerzburg When pathogens invade the human body, a rapid response is required. At the forefront of the immune response are special immune cells. They reside in various tissues such as the lungs, liver, skin...

by Karolinska Institutet Credit: Pixabay/CC0 Public Domain Researchers at Karolinska Institutet in Sweden have analyzed and described in detail the immune cells residing in the human bile duct. The findings may pave the way for new treatment strategies against disorders of the bile duct, which are often linked to immunological processes. The study is published in the...
by Max Planck Society Neutrophils (green) form cell swarms and accumulate at tissue sites where they need to contain damaged cells or invading microbes. Multicolored trajectories of neutrophil migration paths are displayed. Credit: MPI of Immunobiology & Epigenetics/ T. Lämmermann Neutrophils belong to the first responders of our immune system. They circulate in our bodies and...
