Yep! Mast cells are activated when IgE antibodies bind to a mast cell receptor. When IgE then binds to the one object it was designed to find, you get mast cell degranulation. This releases histamines along with a few other chemicals. Degranulation is our immune defense against parasites, so you got a head start for parasite defense for sure! But desensitization can be achieved, which makes IgG antibodies bind to the foreign object before IgE has the chance. I’d think this could be a possible treatment for the syndrome.
Do you also have asthma? The same IgE’s also bind to eosinophil’s. Mast cell degranulation in the lungs leads to acute asthma, whereas when eosinophil’s join the party it causes airway remodeling, aka chronic asthma.

I don’t have asthma. I don’t even think I have any IgE involvement. My total IgE tests at low/normal levels, I don’t seem to have eosinophil involvement that I am aware of. I haven’t even had anaphylaxis before. Though my mast cells constantly degranulate in response to histamine liberators like pepper, chilli, tomato, mustard or triggers like vibrations (shower water on my skin or electric toothbrush), or like laundry scents or perfumes or quick temperature fluctuations. Gives me maad fatigue, lots of hintamine release, blood thinning, etc. Have to avoid triggers and take a bunch of things I found that stabilise mast cells and then I feel good. I have mutations in my methylation and metabolism genes which drains my (acetyl)choline too so probably related somehow.

While there’s no free floating IgE in your system, to degranulate mast cells need IgE bound to their surface. Thats the activation aspect. Since you need mast cells, it’s not exactly something you can turn off. Glad you know the triggers at least, gives you the opportunity to make moves accordingly!

They always need IgE to activate? How does this work for triggers that have no antigen, e.g. vibrations? Is there any way to identify what the mast cell bound IgE are reacting/binding to?
I understand that there are cases where spinal decompression surgery has cured mast cell activation syndrome. It seems to be related to spinal compression in some cases including mine. Any idea how that could possibly be tying in?
