Spontaneous rosetting characteristics of prostaglandin (PG)-treated lymphocytes from patients with solid neoplasias

Lymphocytes forming spontaneous rosettes with mouse erythrocytes (ME) were studied in 53 patients with solid neoplasias for their sensitivity to prostaglandins (PGs) E 2 and F 1α. While in normal subjects these PGs markedly inhibit ME-rosette formation, this inhibition is greatly reduced in cancer p...

description Lymphocytes forming spontaneous rosettes with mouse erythrocytes (ME) were studied in 53 patients with solid neoplasias for their sensitivity to prostaglandins (PGs) E 2 and F 1α. While in normal subjects these PGs markedly inhibit ME-rosette formation, this inhibition is greatly reduced in cancer patients. Moreover this effect appears not to be dose dependent. These patients' lymphocytes with high-affinity receptors for sheep erythrocytes (early E-rosette-forming cells) were also studied for their sensitivity to PGE 2. In all neoplastic patients a low inhibition of early E rosettes was observed in contrast with the high values found in normal subjects. This marked increase of PG-resistant rosette-forming lymphocytes may be useful for the diagnosis and prognosis of cancer.
