Parallel Tubular Arrays in Severe Combined

The ultrastructure of the lymphocytes from ameter of 36-44 nm. The PTA were mostly three children with severe combined imlocated in the centriolar and Golgi regions munodeficiency disease (SCID) is deof the cytoplasm, and were sometimes scribed. Parallel tubular arrays ( PTA) were membrane bound. A centnolar origin of found in a large percentage of circulating the inclusion was suggested. A second inlymphocytes (53%, 41%, and 13%) in clusion, the tubuloreticular structure, was three SCID patients when compared to found in only 1 .4% of the circulating age-matched controls. The size of these lymphocytes from one SCID patient. The inclusions was quite variable, with some origin of the PTA and its occurrence in attaining a length of 1 .7 m. They consevere combined immunodeficiency distamed a tubular substructure with a diease are discussed.
