Deficient natural killer cell (NK) activity and macrophage functioning in schizophrenic patients
Abstract
The cytotoxic potential of mononuclear blood cells from 27 chronic schizophrenic patients was evaluated using quantitative measures of natural killer cell activity and macrophage inhibition of tumor cell growth. 44% of the patients had some evidence of deficient in vitro mononuclear cell function which was not correlated with a qualitative or quantitative alteration in the histologic appearance of these peripheral blood cells.

Autistic patients showed no decrease in overall NK count, similar to schizophrenia, suggesting that the cells themselves are dysfunctional.
“Autistic patients showed no decrease in overall NK count, a similar result to schizophrenia (DeLisi et al, 1983), suggesting that it is the cells themselves that are dysfunctional.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
