This research project has the potential to make a valuable contribution. I do hope that the experimental design and data analyses are suitably stringent. Sample size and subject composition will be critical.

Does tattooing benefit the immune system? The inking of immunity.
Not surprising that tatooing would change the immune system. Note the need to carefully document the characteristics of the "inks" (and carrier) being used, and all aspects of the piercing method. Ideally, limit subjects to people that only use a single tattoo artists, to allow for an optimum statistical data analysis.
