Identification And Characterization

Erithrophagocytic lymphohistiocytosis is a rare disease characterized by exaggerated histiocytic proliferation and activation12 and multisystem involvement including visceral organs, lymph nodes, bone marrow and central nervous system4. Magnetic Resonance (MR) examination was performed in 10 patients with previously diagnosed Erithrophagocytic lymphohistiocytosis. This study was aimed at assessing MR accuracy in the identification and characterization of central nervous system lesions. MR findings show a good correlation with areas of parenchymal and meningeal lymphohistiocytic infiltration5, demonstrating diffuse white matter abnormalities in the early stages and necrotic areas with parenchymal volume loss as terminal findings4. In addition, MR allows the follow-up after chemotherapy and bone marrow transplantation2,3. Although rare, EL should be differentiated from other pediatric patchy white matter abnormalities5.

Binding Glycoprotein

Here we report the isolation and initial biochemical characterization of a 120-kD peanut agglutinin-binding glycoprotein from the adult human central nervous system (CNS), which is anchored to membranes through a phosphatidylinositol linkage. Myelin incubated with phosphatidylinositol-specific phospholipase C released the protein as a soluble polypeptide of 105 kD, which was isolated with peanut agglutinin-agarose affinity chromatography. The protein was found to be highly glycosylated. The protein appears to be confined to the CNS, where its developmental expression is region specific and parallels myelination. It is in greater quantity in white matter than in gray matter and it is in isolated human CNS myelin. Furthermore, ovine oligodendrocytes in culture contain the protein on their surfaces and release it into the supernatant as a soluble 105-kD form. We call this protein the oligodendrocyte-myelin protein.

A classic preparation of central nervous system tissue (CNS) is the Golgi procedure popularized by Cajal. The method is partially specific as only a few cells are impregnated with silver chromate usualy after osmium post fixation. Samples are observable by light (LM) or electron microscopy (EM). However, the impregnation is often so dense that structures are masked in EM, and the osmium background may be undesirable in LM. Gold toning is used for a subtle but high contrast EM preparation, and osmium can be omitted for LM. We are investigating these preparations as part of a study to develop correlative LM and EM (particularly HVEM) methodologies in neurobiology. Confocal light microscopy is particularly useful as the impregnated cells have extensive three-dimensional structure in tissue samples from one to several hundred micrometers thick. Boyde has observed similar preparations in the tandem scanning reflected light microscope (TSRLM).

Recent Developments

The recent developments of fast reliable docking, virtual screening and other algorithms gave rise to discovery of many novel ligands of histamine receptors that could be used for treatment of allergic inflammatory disorders, central nervous system pathologies, pain, cancer and obesity. Furthermore, the pharmacological profiles of ligands clearly indicate that these receptors may be considered as targets not only for selective but also for multi-target drugs that could be used for treatment of complex disorders such as Alzheimer’s disease. Therefore, analysis of protein-ligand recognition in the binding site of histamine receptors and also other molecular targets has become a valuable tool in drug design toolkit. This review covers the period 2014–2020 in the field of theoretical investigations of histamine receptors mostly based on molecular modeling as well as the experimental characterization of novel ligands of these receptors.

Abstract Previous genetic studies have shown that wild-type function of the l(1)ogre (lethal (1) optic ganglion reduced) locus is essential for the generation and/or maintenance of the postembryonic neuroblasts including those from which the optic lobe is descended. In the present study molecular isolation and characterization of the l(1)ogre locus was carried out to study the structure and expression of this gene in order to gain information about the nature of l(1)ogre function and its relevance to the development of the central nervous system. About 70 kilobases (kb) of genomic DNA were isolated that spanned the region where l(1)ogre was known to reside. Southern analysis of a l(1)ogre mutation and subsequent P element-mediated DNA transformation mapped the l(1)ogre+ function within a genomic fragment of 12.5 kb. Northern analyses showed that a 2.9-kb message transcribed from this 12.5-kb region represented l(1)ogre. A 2.15-kb portion of a corresponding cDNA clone was sequenced. An open reading frame (ORF) of 1,086 base paris was found, and a protein sequence of 362 amino acids with one highly hydrophobic segment was deduced from conceptual translation of this ORF.
