The researchers discovered that once a tattoo is made, the ink rapidly travels through the lymphatic system and, within hours, accumulates in large quantities in the lymph nodes — key organs of the body’s defense system. Inside these nodes, immune cells called macrophages actively capture all types of pigment. This ink uptake triggers an inflammatory response with two phases: an acute phase lasting about two days after tattooing, followed by a chronic phase that can persist for years. The chronic phase is particularly concerning because it weakens the immune system, potentially increasing the susceptibility to infections and cancer. The study also showed that macrophages cannot break down the ink like they would other pathogens, wich causes them to die, especially with red and black inks, suggesting these colors may be more toxic. As a result, ink remains trapped in the lymph nodes in a continuous cycle of capture and cell death, gradually affecting the immune system’s defensive capacity.
The full paper is here and, as usual, it's hardly anything and decontextualized in order to get a publishable result.
This one is so bad that it doesn't use established baselines or do any form of statistical analysis on the results instead opting for their own "baseline" measurements using very small sample sizes. It also plays a smoke and mirrors game where it shows a result for short term immunological response and then uses that to insinuate the 'slightly reduced but still likely well within the error of the poor control' long term effects are worth noting.
Other major flaws:
At best it's a very poorly communicated and poorly designed experiment but I suspect that's due to it result hunting.
Thanks for chiming in, but I'm not sure I understand the implications. It's not trustworthy ? I shouldn't listen to the conclusions ?
What the hell? Was this even peer reviewed?
Probably by LLMs.
Oh honey... This is barely below average.
