Dr. Robert Whitfield explains that Breast Implant Illness involves persistent Th1 immune activation, which can drive chronic inflammation and fatigue. A study exposed naive human CD4-positive T cells to purified Tinhome for 48 hours to test whether this agent directly triggers the Th1 response.
That matters because BII is described as a systemic illness. The study found a systemic immune signature that parallels the local tissue findings. So when people ask me, can this cause, you know, these symptoms, I say yes. The persistent Th1 activation can contribute to the chronic inflammation and is biologically consistent with symptoms such as fatigue and others that we see. It is not specific to BII. However, it does not by itself— And, and by itself it doesn't explain every symptom. So another question remained: did Tinham actually drive the Th1 response, or were the 2 findings like just simply happening at the same time? So you can see, I mean, not only was this extremely well-done study, it really answers a lot of these questions that come up. The researchers isolated naive human CD4-positive T cells from healthy donors. These mean they had not— let's go back. I just want to make sure that we go over this. So the naive means that these cells had not yet committed to a specific T helper subtype, so not Th1, not yet. Okay, so that's important. So the investigators exposed the T cells, these naive ones, to the purified Tinhome for 48 hours.
