The endocytic accessory clathrin assembly lymphoid myeloid leukemia protein (CALM) is the ubiquitously expressed homolog of the neuron-specific protein AP180 that has been implicated in the retrieval of synaptic vesicle. Here, we show that CALM associates with the alpha-appendage domain of the AP2 adaptor via the three peptide motifs 420DPF, 375DIF and(More)
Hereditary pulmonary alveolar proteinosis (herPAP) is a rare lung disease caused by mutations in the granulocyte-macrophage colony-stimulating factor (GM-CSF) receptor genes, resulting in disturbed alveolar macrophage differentiation, massive alveolar proteinosis, and life-threatening respiratory insufficiency. So far, the only effective treatment for(More)
We have characterized a novel clathrin-binding 68-kDa epsin N-terminal homology domain (ENTH-domain) protein that we name clathrin interacting protein localized in the trans-Golgi region (Clint). It localizes predominantly to the Golgi region of epithelial cells as well as to more peripheral vesicular structures. Clint colocalizes with AP-1 and clathrin(More)
Embryonic stem cells (ESCs) from mice and humans (hESCs) have been shown to be able to efficiently differentiate toward cardiomyocytes (CMs). Because murine ESCs and hESCs do not allow for establishment of pre-clinical allogeneic transplantation models, the aim of our study was to generate functional CMs from rhesus monkey ESCs (rESCs). Although formation(More)
Receptor-mediated endocytosis of ligands, such as transferrin and LDL, is suppressed when clathrin synthesis is blocked by RNA interference in HeLa cells. We have found that domains containing the adapter complex 2 (AP2)-coated vesicle adapter and the endocytic accessory proteins CALM (clathrin assembly lymphoid myeloid leukemia protein), epsin, and(More)
UNLABELLED The recommended treatment for full-thickness macular holes is removal of the posterior hyaloid and sometimes the epiretinal membrane from the retina during vitrectomy in order to release the assumed intravitreous traction. We have employed a technique involving the additional removal of the membrana limitans interna (MLI) from the retina in the(More)
Two new components of basal laminar deposit (BlamD) occurring in samples of submacular neovascular membranes surgically removed from patients with a wet (exudative) form of age-related macular degeneration are described. They are: (1) minute ribbon-like structures which occur singly and/or in a bunch and extend from the inner surface of the BlamD layer into(More)
In the human small intestine, proliferation, migration, differentiation and death of epithelial cells take place in separated compartments along the crypt-villus axis. It has been shown in different cell systems that these basic biological activities are influenced by extracellular matrix proteins. To investigate possible relationships in the epithelium of(More)
The present study was designed to evaluate different techniques for the in situ detection of apoptosis in human and rat small intestinal epithelium. The techniques included light microscopy (LM) and transmission electron microscopy (TEM) observation of epoxy resin-embedded tissue, scanning electron microscopy (SEM), TUNEL assay, and antibodies directed(More)
