After stimulation of T-lymphocytes from healthy volunteers with the mitogen phytohemagglutinin (PHA) 40% of the cells exhibit an oscillatory increase in intracellular calcium concentration ([Ca2+]i). During depression the number of cells responding to PHA is reduced to 20%. These cells show a marked decrease in [Ca2+]i-reaction to stimulation and flattened oscillations. This reduction of mitogen-induced Ca2+ signals in T-cells of depressed patients appears to be a reliable state marker in depressive illness and is reversed upon successful treatment with interpersonal psychotherapy (IPT).
用促细胞分裂剂植物血凝素(PHA)刺激健康志愿者的T淋巴细胞后,40%的细胞表现出细胞内钙浓度([Ca2+]i)的振荡性增加。在抑郁期间,对PHA有反应的细胞数量减少到20%。这些细胞对刺激的[Ca2+]i反应明显降低,振荡变平缓。抑郁症患者T细胞中促细胞分裂剂诱导的Ca2+信号的这种减少似乎是抑郁症的一个可靠状态标志物,并且在人际心理治疗(IPT)成功治疗后会逆转。
