As a surfactant, sodium ricinoleate is an irritant to human skin and mucus membranes, causing hypersensitivity responses.

Professor Dieli's research has covered several aspects of human immunology: delayed-type hypersensitivity responses, immune response against Mycobacterium tuberculosis and cancer immunotherapy.

The fraction exhibited the ability to augment delayed-type hypersensitivity response against sheep red blood cells in mice and to decrease the cytotoxic activity of natural killer cells.

Still experimental, skin tests with soluble extracts of human or bovine uveal tissue are said to elicit delayed hypersensitivity responses in these patients.

When the immune system responds to very low levels of antigen that it usually shouldn't respond to, a hypersensitivity response occurs.

In thymectomized animals, the ability to reject allografts, and to mount delayed hypersensitivity responses, was drastically reduced.

The presumed mechanism of liver injury in SSZ hepatotoxicity is an idiosyncratic hypersensitivity response.

Delayed-type hypersensitivity responses induced by bovine colostral components.

Over time, there is the risk of serum sickness, which is a delayed hypersensitivity response to the medication.

These responses were monitored by injecting uninfected, irradiated tumor cells into the skin and looking for delayed-type hypersensitivity responses.
