Journal of Immunology, 1987
We have previously shown that at least two types of Lyt-1+, Lyt-2-, L3T4+ helper T cell clones can be distinguished in vitro by different patterns of lymphokine secretion and by different forms of B cell help.

Impaired Delayed Hypersensitivity
JAMA: The Journal of the American Medical Association, 1968To the Editor:— I was very much interested in the report of Waldorf et al (203:831, 1968) concerning the impairment in skin reactivity of older individuals after the induction of delayed skin test reactions by the application of patch tests of 2, 4-dinitrochlorobenzene (DNCB).

Induction of ‘Delayed’ Hypersensitivity
Nature, 1962IT is well known that the ‘delayed’ or ‘infectious’ type of sensitivity is induced in a normal organism, after contact with living or killed tubercle bacilli, but it is not passively transferred by means of serum or extracts of organs from ‘allergic’ animals.

Delayed Hypersensitivity in the Mouse
1975Publisher Summary This chapter discusses the delayed-type hypersensitivity (DTH), the prototype model of cellular immune phenomena as it occurs in mice. Most of the recent explosive development in the field of cellular immunology has emphasized the in vitro demonstrations of cellular responses to immunologic challenge and the various products of ...

Delayed hypersensitivity in mice
Journal of Allergy, 1959Abstract A new technique has been used to show that white mice can develop delayed hypersensitivity to tubercle bacilli. The technique consists of determining mouse lung densities after intravenous challenge with these bacilli, increased densities indicating the delayed allergic reaction. Aside from its high sensitivity, this method takes advantage of

Summary Pre-exposure of sensitized guinea pig peritoneal exudate cells to antigen renders them incapable of migration inhibition in capillary tubes. However, pre-exposure to the same antigen did not affect migration inhibition of heterologously sensitized cells.

Hypersensitivity, Delayed Type*
2005Hypersensitivity reactions occur when the immune system acts in an exaggerated manner leading to tissue damage. Delayed hypersensitivity is an immunologic reaction that is mediated primarily by T cells and monocytes and presents hours to days after the antigen crosses into the skin.

Aspirin and Delayed Type Hypersensitivity
Arthritis & Rheumatism, 1977AbstractThe effects of aspirin on delayed hypersensitivity were assessed in 40 healthy subjects who were randomly assigned to two equal groups. In a double‐blind format, the individuals in one group were placed on 4 gm aspirin daily for 5 days, and individuals in the other group were given placebo.
