Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

open access: yesNew Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Delayed‐Type Hypersensitivity

Current Protocols in Immunology, 2001
AbstractDelayed‐type hypersensitivity (DTH) is an in vivo assay of cell‐mediated immune function. DTH reactions are often divided into two phases: the sensitization phase, referring to the initial immunization with specific antigen, and the efferent or challenge phase of the DTH response, which usually follows 6 to 14 days after sensitization.

Impaired Delayed Hypersensitivity

JAMA: The Journal of the American Medical Association, 1968
To 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).

Delayed Hypersensitivity

The Journal of Immunology, 1969
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.

Delayed hypersensitivity to bosentan

Allergy, 2009
This is the first case of a cell-mediated hypersensitivity to bosentan diagnosed on the basis of positive responses to the lymphocyte transformation test and a challenge. However, the latter provoked a severe reaction (DRESS)
