‘‘Green Odor’ ’ Inhalation Reduces the Skin-Barrier Disruption Induced by Chronic Restraint Stress in Rats: Physiological and Histological Examinations
"... We investigated whether inhalation of green odor (a mixture of equal amounts of trans-2-hexenal and cis-3-hexenol) prevents the skin-barrier disruption induced by chronic restraint stress in rats. To this end, transepidermal water loss (TEWL) was measured as an index of the disruption of skin-barrie ..."

that rats in the green odor + stress group possessed sufficient intercorneocyte lipids to create an effective skin barrier, although these had apparently been decreased in the vehicle + stress group. Daily administration of DEX for 14 days increased TEWL. The present results suggest that chronic stress
Can cuticular lipids provide sufficient information for withincolony nepotism in wasps
- Proceedings of the Royal Society of London, Series B
, 2004
"... Inclusive fitness theory predicts that members of non-clonal societies will gain by directing altruistic acts towards their closest relatives. Multiple mating by queens and multiple queens creates distinct full-sister groups in many hymenopteran societies within which nepotism might occur. However, ..."

, the weight of empirical data suggests that nepotism within full-sister groups is absent. It has been suggested that a lack of reliable recognition markers is responsible. In this paper, we investigated whether epicuticular lipids could provide reliable cues for intracolony kin recognition in two species
Domain 3 of Hepatitis C Core Protein is Sufficient for Intracellular Lipid Accumulation
"... Background—Hepatitis C virus (HCV) is a major cause of liver disease worldwide with steatosis, or “fatty liver”, being a frequent histologic finding. In previous work, we identified sequence polymorphisms within domain 3 (d3) of genotype 3 HCV Core protein that correlated with steatosis and in vitro ..."

and in vitro lipid accumulation. In this study, we investigated the sufficiency of d3 to promote lipid accumulation, the role of HCV genotype in d3 lipid accumulation and the subcellular distribution of d3. Methods—Stable cell lines expressing green fluorescent protein (GFP) fusions with HCV Core d3 from
An Increase in Peroxisomal Fatty Acid Oxidation Is Not Sufficient to Prevent Tissue Lipid Accumulation in hHTg Rats

Selenium and Vitamin E Sufficiency in Premature Infants Requiring Total Parenteral Nutrition
"... ABSTRACT. A randomized prospective study of LBW infants was undertaken to evaluate the effect of parenteral lipid infu-sions upon their antioxidant systems. Ten babies received a parenteral nutrition regimen with lipid emulsion, and ten re-ceived a regimen without lipid. Although the addition of lip ..."

for infants receiving TPN with lipids in regard to vitamin E and selenium sufficiency. The purpose of this study was to compare two TPN regimens (with and without lipid) for their effect on the antioxidant systems of LBW infants.
A role for lipid rafts in B cell antigen receptor signaling and antigen targeting
, 1999
"... The B cell antigen receptor (BCR) serves both to initiate signal transduction cascades and to target antigen for processing and presentation by MHC class II molecules. How these two BCR functions are coordinated is not known. Recently, sphingolipid- and cholesterol-rich plasma membrane lipid microdo ..."

the phosphatase CD45R. Both Ig � and Lyn in the lipid rafts become phosphorylated, and subsequently the BCR and a portion of G M1 are targeted to the class II peptide loading compartment. Entry into lipid rafts, however, is not sufficient for targeting to the antigen processing compartments, as a mutant surface
Listeriolysin O Is Necessary and Sufficient to Induce Autophagy during Listeria monocytogenes Infection
"... Background: Recent studies have suggested that autophagy is utilized by cells as a protective mechanism against Listeria monocytogenes infection. Methodology/Principal Findings: However we find autophagy has no measurable role in vacuolar escape and intracellular growth in primary cultured bone marr ..."

a mutant lacking LLO was not. Bacillus subtilis expressing either LLO or a related cytolysin, perfringolysin O (PFO), induced LC3 colocalization and LC3 lipidation. Further, LLO-containing liposomes also recruited LC3-GFP, indicating that LLO was sufficient to induce targeted autophagy
T cell receptor-proximal signals are sustained in peripheral microclusters and terminated in the central supramolecular activation cluster
- Immunity
, 2006
"... T cell receptor (TCR) signaling is initiated and sus-tained in microclusters; however, it’s not known whether signaling also occurs in the TCR-rich central supramolecular activation cluster (cSMAC). We showed that the cSMAC formed by fusion of micro-clusters contained more CD45 than microclusters an ..."

and is a site enriched in lysobisphosphatidic acid, a lipid involved in sorting ubiquitinated membrane proteins for degradation. Calcium signaling via TCR was blocked within 2 min by anti-MHCp treatment and 1min by latrunculin-A treatment. TCR-MHCp inter-actions in the cSMAC survived these perturbations
Self-assembly of copolymers and lipids

Either free and organized into broad lipid bilayers in the intercorneocytes spaces, or covalently bound to the corneocyte envelope, they play a crucial role in permeability barrier function. This article presents the structures of v ..."
