Resealing of a disrupted plasma membrane requires Ca(2+)-regulated exocytosis. Repeated disruptions reseal more quickly than the initial wound. This facilitated response requires both Ca(2+) and protein kinase C (PKC), and is sensitive to brefeldin A. There is also evidence that
Chlamydia pneumoniae is a bacterial obligate intracellular parasite with a developmental cycle common to all members of the genus Chlamydia. Like other chlamydiae, the developmental cycle of C. pneumoniae occurs entirely within a membrane-bound intracellular vacuole, termed an inclusion, that

Ceramide is a bioactive molecule involved in cellular responses to stress and inflammation. The major pathway for ceramide accumulation is via agonist-induced activation of cellular sphingomyelinases. It has also been shown that the ceramide level in circulating low density lipoprotein
Peptides carrying organelle-specific import or retention sequences can target the fluorophore BODIPY(581/591) to the nucleus, peroxisomes, endoplasmic reticulum (ER), or the trans-Golgi network (TGN). The peroxisomal peptide contains the PTS1 sequence AKL. For targeting to the ER or TGN, the

The influence of sterol carrier protein-2 (SCP-2) on the cellular metabolism of sphingolipids was examined in control mouse L-cells and stably transfected clones expressing the protein SCP-2. Three approaches were used to examine for differences; (1) compositional analysis of endogenous
