Cancer immunotherapy may increase risk of developing rheumatologic disorders

Johns Hopkins
Johns Hopkins University researchers have found a link between cancer immunotherapy drugs and an increased risk of developing rheumatologic disorders, which they expect to only be exacerbated as their use increases. They conducted what’s thought to be the largest published study of patients taking i…

Although the checkpoint inhibitors are called targeted therapies, they are not specific. They bind specifically to the cellular receptors they are designed to bind, but they non-specifically up-regulate all activated T-cells regardless of their recognised targets.
So, all’s good if most of the strongly activated T-cells recognise and hunt down the tumour cells or infected cells; not good (disastrous even) if T-cells sensitised to self-antigens go on the rampage. Autoimmunity is the result.
