The cytokin interleukin 11 (IL-11) plays an important role in autoimmune diseases, fibrotic complications, and solid cancers. Blocking IL-11 can extend lifespan and improve health.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body

Structure of novel coronavirus spike receptor-binding domain (pink) complexed with its receptor ACE2 (blue), surface modeel, white background
Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.\n\nThis image was not created by AI.
The NEK-7 independent NLRP3 inflammasome in it's hexameric conformation with ADP (red) bound. Inflammasomes are a promising target for the treatment of autoimmune diseases. PDB entry: 7zgu.
