abstract：:This review describes recent progress concerning the molecular aspects of the Na+/H+ exchanger. The Na+/H+ exchanger is an important regulator for intracellular pH, cell volume, and transepithelial Na+ transport. It exists in virtually all cells with cell type-dependent pattern of isoform expression, and it is regulat...

abstract：:Protein toxins such as ricin and Shiga toxin with intracellular targets have to be endocytosed and translocated to the cytosol to inhibit the protein synthesis and thereby kill the cell. Ricin is internalized by both clathrin-dependent and -independent endocytic mechanisms, whereas Shiga toxin seems to be taken up exc...

abstract：:This review focuses on the molecular stratagems utilized by bacteria, yeast, and mammals in their adaptation to hypoxia. Among this broad range of organisms, changes in oxygen tension appear to be sensed by heme proteins, with subsequent transfer of electrons along a signal transduction pathway which may depend on rea...

abstract：:For many decades, the inability of lesioned central neurons to regrow was accepted almost as a "law of nature", and on the clinical level, spinal cord and brain lesions were seen as being irreversible. Today we are starting to understand the mechanisms of neuronal regeneration in the central nervous system and its pre...

abstract：:The transepithelial movement of fluids, electrolytes, and larger molecules is achieved by the activity of a host of specialized transporting proteins, including enzymes, receptors, and channels, that are located on either the apical, basal, or lateral plasma membrane domains of epithelial cells. In the kidney as well ...

abstract：:In the last few years there has been a veritable explosion of knowledge about cyclic nucleotide phosphodiesterases. In particular, the accumulating data showing that there are a large number of different phosphodiesterase isozymes have triggered an equally large increase in interest about these enzymes. At least seven...

abstract：:The kidneys play a vital role in mineral homeostasis. In this review, the handling of calcium and the methods currently applied to measuring its intracellular concentration are discussed. The bulk of calcium absorption proceeds in proximal tubules, with smaller fractions recovered by thick ascending limbs, distal conv...

Lymphatic smooth muscle within the collecting lymphatics appears further downstream, in some organs only outside the parenchyma. This p...

abstract：:Afferent signals that guide orienting movements converge in the deeper layers of the SC in a wide variety of animals. The sensory cells are arranged topographically according to their receptive-field locations and, thereby, form maps of sensory space. Maps of visual, somatosensory, and/or auditory space have been obta...
