Over the last twenty years, the amount of information related to epitopes recognized in the course of T and B cell-mediated immune responses has dramatically increased. As of June 2004, a PubMed search using the word " epitope " , reveals a total of 5,173 records prior (with a large fraction of the 2004 records still to come). Epitope-based techniques are(More)
We have described the formation of the zebrafish central nervous system. The spinal cord has the simplest organization and was considered first, followed by the forebrain, midbrain and hindbrain. We have discussed many studies that have revealed the molecular mechanisms, including extrinsic signals and intrinsic responses to them, underlying the(More)
Recent studies in mouse suggest that the extraembryonic endoderm has an important role in early embryonic patterning [1]. To analyze whether similar mechanisms operate in other vertebrates, we cloned the zebrafish homologue of Hex, a homeobox gene that is expressed asymmetrically in the mouse visceral endoderm [2]. Early expression of zebrafish hex is(More)
N-cadherin (Ncad) is a classical cadherin that is implicated in several aspects of vertebrate embryonic development, including somitogenesis, heart morphogenesis, neural tube formation and establishment of left-right asymmetry. However, genetic in vivo analyses of its role during neural development have been rather limited. We report the isolation and(More)
Autosomal dominant mutations that activate the leucine-rich repeat kinase 2 (LRRK2) cause inherited Parkinson's disease. Recent work has revealed that LRRK2 directly phosphorylates a conserved threonine/serine residue in the effector-binding switch-II motif of a number of Rab GTPase proteins, including Rab10. Here we describe a facile and robust method to(More)
Interleukin-2 inducible tyrosine kinase (ITK) is expressed in T cells and plays a critical role in signalling through the T cell receptor. Evidence, mainly from knockout mice, has suggested that ITK plays a particularly important function in Th2 cells and this has prompted significant efforts to discover ITK inhibitors for the treatment of allergic disease.(More)
