Further to validate the outcomes, the staff discovered that in mice after being pregnant, the breast epithelial cells (which line lactation ducts) produce a selected protein known as CD1d, with out which there was no improve in NKT cells.

Moreover, absence of NKT cells led to the cancerous formation of the epithelial cells. Hence, the staff affirmed that CD1d molecules had been accountable for inviting within the NKT cells for additional monitoring the epithelial cells within the breast tissue for tumors after being pregnant.

The staff is now additional set to discover the leads to people.
