Induction of tumor necrosis factor alpha was studied in the brain of rats after focal cerebral ischaemia by occlusion of the left middle cerebral artery. Using a specific antisense riboprobe for in situ hybridization histochemistry, cells positive for tumor necrosis factor alpha messenger RNA were detected within 30 min in the brain regions known to be(More)
Membrane currents of cultured human monocytes and rat microglia were recorded with the whole-cell patch clamp technique. Freshly isolated monocytes or resting (proliferating) microglia express only inwardly rectifying K+ channels. However, incubation in teflon bags leads to the expression of additional, outwardly rectifying K+ channels. The outward K+(More)
Primary mRNA transcripts in several systems are edited by single base substitutions, small deletions or insertions to yield functional messenger RNA species. Mitochondrial mRNAs in particular, including those from plants, seem to be the subject of extensive editing, unlike mRNAs encoded by chloroplast DNA, for which the prediction of amino-acid sequence(More)
The induction of the heat shock response in Lactococcus lactis subsp. cremoris strain MG1363 was analysed at the RNA level using a novel RNA isolation procedure to prevent degradation. Cloning of the dnaJ and groEL homologues was carried out. Northern blot analysis showed a similar induction pattern for dnaK, dnaJ and groELS after transfer from 30 degrees C(More)
The high-affinity receptors for interleukin-3 (IL-3), GM-CSF, and IL-5 are composed of a ligand binding (alpha-) and a transducing (beta-) subunit. Two distinct transducing subunits (clones AIC2A and AIC2B) have been cloned from mouse, whereas in humans, only one (common) beta-subunit (beta c) has been found. A PCR-based cloning strategy was used to obtain(More)
Interleukin-3 (IL-3, multi-CSF) is a growth factor for a variety of hematopoietic progenitor cells. Recently, microglial cells, the resident macrophages of the central nervous system (CNS) have been shown to proliferate in the presence of IL-3 both in vivo and in culture. Data obtained from cultured astrocytes gave rise to the hypothesis that astrocytes(More)
The function of interleukin-3 (or multi-CSF) in the hemopoietic system has been studied in great detail. Although its growth promoting activity on brain microglial cells has been confirmed both in vitro and in vivo, its presence in the brain and even in cultured brain cells has repeatedly been questioned. We have shown recently that isolated rat microglia(More)
Aggression is a common management problem for child psychiatry hospital units. We describe an exploratory study with the primary objective of establishing the feasibility of linking salivary concentrations of three hormones (testosterone, dehydroepiandrosterone [DHEA], and cortisol) with aggression. Between May 2011 and November 2011, we recruited 17(More)
