Abstract
The binding of three influenza A and one influenza B virus strains to proteins of three continuously cultured cell lines was studied using protein overlay and immunostaining methods. The results obtained indicated the presence of both sialic acid-dependent and -independent binding of the virus strains; virus binding to proteins in the molecular mass range from about 40 to 103 kDa was dependent on sialic acid, whereas binding to the 33 kDa protein was independent of sialic acid. The 33 kDa binding protein was identified as annexin, a widely distributed non-glycosylated calcium-dependent phospholipid-binding protein.

Abstract
Fluorescent dansyl derivatives of 3 natural sphingolipids (gangliosides, cerebroside and sphingomyelin) were shown to be readily taken up by culture cells (HeLa-, MDCK- and primary rat brain cells). A part of the incorporated fluorescent sphingolipids remained associated with the cells after incubation in a culture medium containing serum, showing a cellular integration of these lipids. Microscopical studies indicated a localization of incorporated lipids in distinct subcellular regions; whereas dansyl cerebroside densely stained structures suggestive of the cytoskeleton and the actin filament, dansyl sphingomyelin and dansyl gangliosides were primarily associated with the plasma membrane. The findings are consistent with the current views on the arrangement of sphingolipids in animal cells.

Abstract
The effect(s) of bovine brain ganglioside-GM1 on the order of phosphatidylcholine-cholesterol membranes were studied using steady-state fluorescence polarization (FPZ) techniques with 1,6-diphenyl-1,3,5-hexatriene (DPH) as the membrane probe. In the absence of cholesterol, GM1 (30 mol%) increases both membrane order and the phase transition temperature of dipalmitoylphosphatidylcholine (DPPC) and dimyristoylphosphatidylcholine (DMPC) membranes. However, in the presence of cholesterol (0.3 or 0.5, cholesterol/phospholipid molar ratio), GM1 significantly decreases steady-state anisotropy (rs) at temperatures above the Tm for the particular phospholipid. This effect may, in part relate to a dilution of membrane cholesterol and is shared by bovine brain sphingomyelin (SM). GM1 (30 mol%) increases the order of 1-palmityl-2-oleyl-PC (POPC) membranes. However, in the presence of cholesterol (0.3 molar ratio) GM1 neither increases or decreases order. Thus, in cholesterol containing artificial membranes, the effect of GM1 depends on the phosphatidylcholine (PC) fatty acid composition and may not be evident from the effect of GM1 on pure PC membranes.

Abstract
Native Ricinus communis agglutinin (RCA 60) has been used as a visual marker to localize the ganglioside GM1 under a variety of conditions in model membranes. By employing the technique of freeze-etch electron microscopy, it was possible to resolve membrane structural details down to some 3 nm. The most striking feature was frequent existence of the marker lectin in clusters--presumably reflecting the underlying presence of clustered receptor. This feature persisted at glycolipid concentrations from 0.5 to 7 mol %. It was visible in membranes of single pure phospholipids above and below their phase transition temperatures, in membranes of mixed phospholipids, and in membranes containing cholesterol. The presence of cations, including Ca2+, was not seen to alter the pattern of lectin binding at a resolution of 3 nm. In pure dipalmitoyl phosphatidylcholine, a lining-up of glycolipid in the "troughs" between ripples in rigid lipid was apparent, in agreement with a similar phenomenon reported by Tillack et al for a neutral glycosphingolipid in pure dimyristoyl phosphatidylcholine [1982: Biochim Biophys Acta 691:261-273]; but this feature was not evident in host matrices composed of several different lipids.

Abstract
Freeze-etch electron microscopy, a platinum shadowing technique, has been used to compare the lateral distribution of several gangliosides in bilayer model membranes by directly visualizing bound lectin molecules. In particular, GM1 and GD1a, major components of brain ganglioside, were studied in phase-separated mixtures of dipalmitoyl- and dielaidoylphosphatidylcholines exposed to Ricinus communis agglutinin and wheat germ agglutinin. The distribution of glycolipid showed evidence of microheterogeneity in that bound lectin tended to occur in clusters of several or more molecules. With GD1a as receptor such clusters were small and very uniformly distributed over the membrane surface. Somewhat larger, irregularly spaced clusters of up to a dozen lectin particles were more typical of membranes bearing GM1 and, in addition, there were occasional extensive patches of bound lectin coexisting with areas apparently devoid of glycolipid receptor in phase-separated mixtures of dipalmitoyl- and dielaidoylphosphatidylcholine. Gangliosides in the latter mixtures were not obviously influenced in their lateral distribution by the presence of coexisting fluid and rigid domains. These basic observations seem to extend to bilayer membranes containing mixtures of two gangliosides. The patterns of lectin binding were not grossly affected by incubation time or history of warming and cooling. This study was extended to bilayers of pure dipalmitoylphosphatidylcholine in expectation that the distinctive features characteristic of the P beta' phase of this lipid might accentuate any behavioural differences between GM1 and GD1a. GM1 was found to exist preferentially in the 'trough' regions between P beta' ripples, while GD1a showed no apparent preferential arrangement. Given that bound lectins adequately reflect glycolipid distribution in membranes, it would appear that structurally different glycolipids from the same host membrane can assume different distributions on the basis of interactions with defined lipid host matrices.

Abstract
In order to diagnose Krabbe's disease (globoid cell leukodystrophy) or its carrier state in patients, galactocerebroside beta-galactosidase (galactosylceramidase) activity in cultured skin fibroblasts was measured with high-performance liquid chromatography using a fluorescent analogue of galactocerebroside, 1-O-galactosyl-2-N-(1-dimethylaminonaphthalene-5-sulfonyl)-sphingosine, as substrate. The enzyme activities in skin fibroblasts of the patients were found to be dramatically reduced when compared with those of controls. The assay can be adopted for diagnostic use in place of assays using radioisotope-labeled natural substrate.

Abstract
Myxoviruses (influenza virus and paramyxovirus) enter host cells by two successive steps consisting of attachment and fusion between viral and cellular membranes. The initial attachment is known to occur through specific binding of the viruses with the neuraminic acid-containing receptors of cellular membranes. Evidence is presented here that, in the following step of membrane fusion, neutral glycolipids terminating in galactose and certain phospholipids (primarily lecithin and sphingomyelin) interact with the viral envelopes and that this interaction may be fundamental to the fusion process.

Abstract
Human neural cells in exponential growth phase were transferred to a serum-free medium and maintained for 72 hr without any detectable loss in viability. The two normal fetal cell lines (CHI and CHII) showed a serum-dependent cell proliferation, but the glioblastoma multiforme cells (12-18) were able to continue proliferating in this totally synthetic medium. The incorporation of [3H]thymidine into the acid-precipitable fraction of both normal and neoplastic human neural cells was assayed in the presence and the absence of exogenous gangliosides by a convenient new method. In serum-free medium, gangliosides (50 microM) inhibited the thymidine incorporation into the normal fetal cells within 24 hr and, in serum containing medium, reduced their proliferation within 48 hr. No such effects were detectable in the glioma cells. The inhibition of thymidine incorporation in the normal cells was reversible upon removal of the gangliosides. These results indicate a role of gangliosides in the postmitotic phase of normal human neural cells resulting in the regulation of cell proliferation.

Abstract
The fluorescence depolarization of 1,6-diphenyl-hexatriene was used to study the dynamic properties of the hydrophobic regions of the lipid envelopes of ortho- and paramyxoviruses as well as of the Rous sarcoma virus and of the membrane lipids of susceptible and nonsusceptible cells. The systems investigated where active and inactive influenza viruses, and NDV virus acting on chick embryo fibroblasts and Rous sarcoma virus acting on susceptible (C/E) and nonsusceptible (C/B) chicken-cell. Polarization degrees and mean rotational correlation times of DPH embedded in viral lipids were significantly higher than those of DPH in the cell membranes, due to a higher rigidity of the virus envelopes. When suspensions of labelled viruses and unlabelled cells or unlabelled viruses and labelled cells were mixed, a characteristic change of the fluorescence polarization degrees with time was observed. This behaviour was ascribed to label transfer from virus to cell membranes or vice versa. While the rate constants of label transfer from virus to cells and cells to virus were about the same for the penetrating viruses the rate constants of label release from inactive virus to cells were much larger than for the migration in the opposite direction.
