When lab-grown human immune cells are exposed to PHA or TNP, they start dying in different ways depending on how much and how long they’re exposed, and both chemicals harm the cells more the longer or stronger the exposure.

Intracellular inflammatory signalling cascades in human monocytic cells on challenge with phytohemagglutinin and 2,4,6-trinitrophenol

Cross-Sectional Study

In Vitro

2022 Feb

The study gave THP-1 immune cells PHA and TNP and found that both hurt the cells in ways that get worse with more dose or longer time, and that each chemical kills cells in a different way — just like the claim said.

Similar Assertions

When these two chemicals are added to human immune cells in a dish, the cells turn on genes and internal pathways that are usually used to signal inflammation — like sounding an alarm.

PHA and TNP are foreign substances that the body’s first-line immune cells recognize as threats, causing them to start an inflammatory response — like raising an alarm bell.
