The A5 antigen is a neuronal cell surface protein of Xenopus presumed to be involved in the neuronal recognition between the optic nerve fibers and the visual centers. Analyses of cDNA clones revealed that the A5 antigen is a class I membrane protein containing two different internal repeats in the extracellular segment. The first repeat bears homology to(More)
We searched for mouse homologues of the cell adhesion protein plexin which was originally found in Xenopus, and obtained a cDNA encoding a plexin-like protein. We referred to this protein as mouse plexin 1. The overall amino acid identity between mouse plexin 1 and Xenopus plexin was 84%. As in the Xenopus plexin, the extracellular segment of mouse plexin 1(More)
In mice, mitral cells are the major efferent neurons of the main olfactory bulb and elongate axons into a very narrow part of the telencephalon to form a fiber bundle referred to as the lateral olfactory tract (LOT). To clarify the mechanisms responsible for guidance of mitral cell axons along this particular pathway, we co-cultured mouse embryo main(More)
Immunohistochemistry by using monoclonal antibodies named A5 and B2, which specifically recognize cell surface proteins the neuropilin and the plexin, respectively, revealed that olfactory axons in Xenopus tadpoles were classified into several subgroups by virtue of the expression levels of these two cell surface molecules. The vomeronasal axons expressed(More)
Neuropilin is a cell-surface glycoprotein that was first identified in Xenopus tadpole nervous tissues and then in chicken and mouse. The primary structure of neuropilin is highly conserved among these vertebrate species. The extracellular part of the molecule is composed of three domains referred to as a1/a2, b1/b2, and c, each of which is expected to be(More)
BACKGROUND To analyse risk factors that influence the recurrence of endometrioma after laparoscopic excision. METHODS A total of 224 patients who had a minimum of 2 years of post-operative follow-up after laparoscopic ovarian endometrioma excision were studied retrospectively. Recurrence was defined as the presence of endometrioma more than 2 cm in size,(More)
Leukocyte chemoattractants are involved in the inflammatory response act via G protein-coupled receptors. We report the cloning of a novel human gene encoding the putative orphan receptor, C5L2, belonging to a subfamily of C3a, C5a and formyl Met-Leu-Ph receptors that are related to the chemokine receptor family. C5L2 transcript levels were abundant in(More)
OBJECTIVE Methotrexate (MTX) is most widely used for the treatment of rheumatoid arthritis (RA). However, it has certain drawbacks with regard to individual differences in its therapeutic effects as well as the differences in the patients' response to MTX therapy. We investigated whether multi-drug resistance-1 (ABCB1) C3435T, reduced folate carrier-1(More)
The early-generated neurons designated as lot cells specifically mark the future site of the lateral olfactory tract (LOT) and guide LOT axons. We investigated the mechanism of how lot cells develop and get localized in the LOT position. Lot cells differentiated from neuroepithelial cells in all regions of the neocortex but not from those in the ganglionic(More)
During development, mitral cells, the main output neurons of the olfactory bulb, project axons into a very narrow part of the telencephalon and form an axonal bundle called the lateral olfactory tract (LOT). The present study shows that before the first mitral cell axons elongate, the LOT position is already marked with a subset of early-generated neurons(More)
