The patient’s antibodies blocked the signalling that triggers T-cell movement from the thymus and lymph nodes into blood and then into many organs.

The researchers then explored whether the woman’s antibodies effectively could inhibit an autoimmune response in mice.

Antibodies against the S1P receptor, created from the patient’s antibody-producing cells, were injected into mice that were induced to develop colitis.

The result was a significant reduction in severity of their diseases, including colitis-associated weight loss, in those mice compared to mice that did not receive the antibodies.

"These results have broad biological implications, since the cells that carry out our immune responses are present in every organ," said Goetzl, director of UCSF Allergy and Immunology Research.

The study appears in online edition of "The FASEB Journal," the official journal of the Federation of American Societies for Experimental Biology.
