Hypersensitivity, Delayed Type*

2005
Hypersensitivity 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.

Delayed Hypersensitivity in vitro

Nature, 1967
DURING investigations of the effects of induced immune paralysis on delayed hypersensitivity in vivo and in vitro, evidence has been found1,2 for a diffusible factor which is released from the sensitive cells in contact with the antigen; this factor inhibits migration of cells from a normal lymph node explant.

Delayed Drug Hypersensitivity Reactions

Annals of Internal Medicine, 2003
Immune reactions to small molecular compounds, such as drugs, can cause a variety of diseases involving the skin, liver, kidney, and lungs. In many drug hypersensitivity reactions, drug-specific CD4+ and CD8+ T cells recognize drugs through their alphabeta T-cell receptors in an MHC-dependent way. Drugs stimulate T cells if they act as haptens and bind

Induction of ‘Delayed’ Hypersensitivity

Nature, 1962
IT 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 Cutaneous Hypersensitivity Testing

Southern Medical Journal, 1982
The topic of delayed cutaneous hypersensitivity testing is reviewed. When skin tests are used to determine whether an individual is anergic, T cell immunity is evaluated. Skin testing can be used to determine the causative organisms of infection or to discover an immunologic deficiency state.

Delayed-Type Hypersensitivity Determination

2012
Delayed-type hypersensitivity responses in the skin (in the case of mice, in the foot pad) is used to assess cell-mediated immunity (CMI) in vivo. In the case of CMI to Helicobacter infection, the mice are given an injection of cultured Helicobacter organisms into the hind footpad, and induration is measured at the site of inoculation 24 h after ...

Delayed hypersensitivity in mice

Journal of Allergy, 1959
Abstract 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
