Patient discussion about mechanics

Q. How does an allergic response occur? I don’t understand the exact mechanism of allergies. Can someone explain this?

A. In the early stages of allergy, a type I hypersensitivity reaction against an allergen, encountered for the first time, causes a response in a type of immune cell called a TH2 lymphocyte, that interact with other lymphocytes called B cells, whose role is production of antibodies. The secreted IgE antibody circulates in the blood and binds to an IgE-specific receptor (a kind of Fc receptor called FceRI) on the surface of other kinds of immune cells called mast cells and basophils, which are both involved in the acute inflammatory response. The IgE-coated cells, at this stage are sensitized to the allergen. If later exposure to the same allergen occurs, the allergen can bind to the IgE molecules held on the surface of the mast cells or basophils and cause a full reaction.

Nevertheless, the point at which the above supertask acquires special theoretical importance appears in connection with the problem of determinism in Newtonian particle mechanics. In discussing this problem, John Earman (1986) mentions several examples of particle systems (pointwise or not, and in finite or infinitely denumerable number), the evolution of which implies that Newtonian particle mechanics is not completely deterministic.
