Hedgehog proteins: expression and function in the thymus

نویسنده

چکیده

Evidencias crecientes demuestran que los morfógenos clásicos, altamente conservados durante la evolución y tradicionalmente implicados en el desarrollo embrionario, donde determinan diferenciación celular y patrones de desarrollo, son expresados en tejidos adultos, como son la médula ósea y el sistema inmunitario. Estas moléculas podrían ser piezas importantes del rompecabezas que orquesta la diferenciación y la homeostasis del sistema inmune, aunque sea sólo recientemente cuando estamos comenzando a entender donde encajan en el entramado del sistema inmune. En esta revisión, describimos la ruta de señalización de las proteínas Hedgehog (Hh) centrándonos en su implicación en la diferenciación de las células T y su posible conexión con otros morfógenos, como son las proteínas morfogénicas del hueso (Bone Morphogenetic Proteins, BMPs)

The role of the desert hedgehog signaling pathway during degeneration and regeneration of peripheral nerves

The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...

Gli 1 protein expression in different types of basal cell carcinoma

Background and aim: Basal cell carcinoma (BCC) is the most common cancer in humans. Activation of Hedgehog (Hh) signal has a key role in development of BCC. The end result of Hedgehog signal are Gli proteing. Gli 1 is a member of this family which activates DNA transcription. Previous studies showed increased expression of Gli 1 in BCC.Materials and methods: In this study 38 pathologic samples ...

CHARACTERIZATION OF HIGH MOBILITY GROUP NONHISTONE PROTEINS FROM DIFFERENTIATED NEUROPHILIC GRANULOCYTES

The quantitative changes of the high mobility group (HMG) nonhistone chromosomal proteins in nondividing, differentiated peritoneal exudate neutrophils were identified by their solubility, electrophoretic mobility on both SDS and acetic acid gels, densitometric traces and elution profile on CM-sephadex. The results indicated that in neutrophils, HMGl undergoes a considerable reduction (80%...

Performance of methylation and expression fluctuations of sonic hedgehog genes in gastric adenocarcinoma

Gastric cancer (GC) is considered as one of the most serious cancers, and in Iran, due to environmental factors in different regions, it has a high frequency. Apart from environmental factors, genetic and epigenetic ones also play a key role in the development of carcinogenesis of GC. In this regard, the study of functioning of the molecular mechanisms involved in the carcinogenesis and also tu...
