seems to be more difficult than that, here it sounds like it is a whole cascade triggering a type 2 immune reaction:i think this is the article where it says "breaking the skin is enough for a type 2 immune reaction" (not a direct quote, just from the top of my head): https://www.science.org/doi/10.1126/sciimmunol.aat1604 (if it is not i forgot where i got it from)
from: https://pmc.ncbi.nlm.nih.gov/articles/PMC9813923/Large multicellular helminths can trigger potent and polarized type 2 immune responses. Considerable advances in our understanding of the initiation phase of the immune response to helminth infections have been made over the past few years, using experimental models of helminth infection [...]
DAMPs are often released by damaged host cells, as a consequence of these large multicellular parasites trafficking through tissues and causing cellular damage by their sheer physical size and release of proteases. Several DAMPs shown to trigger innate immunity in the context of helminth infection include ATP, chitinase-like proteins, and trefoil factors. In many cases each of these different stimuli are essential for the development of this type 2 immune response, indicating the high threshold required for its initiation.
