How Apigenin Blocks PD-L1 and Unleashes T Cells #immunotherapy #cancer #breakthrough

[00:00:00]Low doses of apigenin have been shown repeatedly to act like estrogen or progesterone and mildly trigger those hormone receptors. Now, don't dismiss that sleep or stress relief benefit.

[00:00:11]This is a stacking opportunity as well.

[00:00:14]We know that cortisol, one of the primary stress hormones, suppresses the immune system. By using apigenin to improve sleep quality and reduce stress, you also lower cortisol and, as we talked about before, you're using multiple different mechanisms to unmask the cancer for your immune system to attack it. When you attack any problem from multiple directions at once, you help prevent resistance from forming and you get better efficacy. Low doses of apigenin have been shown repeatedly to act like estrogen or progesterone and mildly trigger those hormone receptors.

[00:00:46]That is not good for hormone receptor positive breast cancer. However, those effects have been repeatedly shown to be biphasic.

[00:00:55]What the heck does that mean? Biphasic?

[00:00:57]It means that small amounts of apigenin stimulate hormone receptors, but large amounts of apigenin actually suppress the hormone receptors. It works backwards.
