Expression of CD56 isoforms in primary and relapsed adult granulosa cell tumors of the ovary.

Background: Adult granulosa cell tumors of the ovary (GCTs) are sex cord stromal tumors of unpredictable behaviour. Up to now, the prediction of the relapsing/malignant potential remains difficult. CD56 (NCAM) in GCTs was previously described in only two studies.

Leukemia inhibitory factor differentially regulates capsaicin and heat sensitivity in cultured rat dorsal root ganglion neurons.

Thermal hyperalgesia is one hallmark of neuropathic pain conditions. Although the exact pathophysiological mechanisms remain elusive, nerve growth factor (NGF) and leukemia inhibitory factor (LIF) are considered key mediators. Their local availability or synthesis are altered by nerve damage and, in turn, they entail changes in phenotype of affected neurons.

Profiling chemokines, cytokines and growth factors in human early pregnancy decidua by protein array.

Problem: In human decidua, a significant increase of leukocytes including CD56(++)CD16(-) uterine natural killer (uNK) cells and CD14(+) monocytes has been observed with the onset of pregnancy. The mechanisms required for the recruitment of those cells to the uterus are still under debate. Cytokines and chemokines have been suggested as key factors for the regulation of these complex cellular migration and interaction processes.
