Cocaine addiction has been associated with changes in synaptic plasticity, mediated in part by neurotrophin cascades. Given sex differences in cocaine addiction, we wanted to assess whether estradiol alters signaling of the brain-derived neurotrophic factor (BDNF), through interaction with its cognate receptor, tyrosine kinase B (Trk B), after repe...
Proteolytic enzymes are ubiquitous and active in a myriad of biochemical pathways. One type, the rhomboids are intramembrane serine proteases that release their products extracellularly. These proteases are present in all forms of life and their function is not fully understood, although some evidence suggests they participate in cell signaling. St...
Research suggests that the medial dorsal nucleus (MD) of the thalamus influences pyramidal cell development in the prefrontal cortex (PFC) in an activity-dependent manner. The MD is reciprocally connected to the PFC. Many psychiatric disorders, such as schizophrenia, affect the PFC, and one of the most consistent findings in schizophrenia is a decr...
Alterations in dendritic spine density following prenatal cocaine exposure were examined in the present study. Timed pregnant rats were injected daily with 30 mg/kg cocaine or saline during gestation. At postnatal day 21, male and female animals were separated and spine density was assessed following Golgi impregnation. In prenatal cocaine-exposed...
