Liver parenchyma shows a remarkable heterogeneity of the hepatocytes along the porto-
central axis with respect to ultrastructure and enzyme activities resulting in different cellular …

Adjacent cells share ions, second messengers and small metabotes through intercellular
channels which are present in gap junctions. This type of intercellular communication …

Das macht das Buch aus: Der „Silbernagel “, wie viele dieses Buch nennen, zeichnet sich
durch die grobe Unterteilung in die zahlreichen klar strukturierten Kapitel aus, die häufig …

Nonsynaptic interactions between neurons have been eclipsed by our increasingly detailed
understanding of chemical synapses, but they do play significant roles in the nervous …

The delineation of key molecular pathways has enhanced our knowledge of the biology of
tumor microenvironment, tumor dissemination, and carcinogenesis. The complexities of cell …

Summary Connexin43 (Cx43) is an integral plasma membrane protein that forms gap
junctions between vertebrate cells. We have used sucrose gradient fractionation and …

We previously demonstrated that the gap junction protein connexin43 is translated as a 42-
kD protein (connexin43-NP) that is efficiently phosphorylated to a 46,000-Mr species …

Embryonic morphogenesis occurs along three orthogonal axes. While the patterning of the
anterior–posterior and dorsal–ventral axes has been increasingly well characterized, the left …

Cannabinoid receptors and their endogenous ligands constitute a novel modulatory system
that is involved in specific brain functions, such as nociception, control of movement …

Two types of calcium (Ca2+) signaling-propagating intercellular Ca2+ waves of increasing
intracellular Ca2+ concentration ([Ca2+] i) and nonpropagating oscillations in [Ca2+] i-co …
