Abstract:

The addition of polyoxyethylene sorbitan monooleate (Tween 80) to a culture of mycobacteria greatly influences cell permeability and sensitivity to antibiotics but very little is known regarding the underlying mechanism. Here we show thatCorynebacterium matruchotii(surrogate of mycobacteria) converts Tween 80 to a structural series of polyoxyethylenic acids which are then used to form novel series-2A and series-2B glycolipids. Minor series-3 glycolipids were also synthesized. The polyoxyethylenic acids replaced corynomycolic acids in the cell wall. Correspondingly the trehalose dicorynomycolat

Abstract Glycolipid and cell surface carbohydrate antigens of human polymorphonuclear neutrophils (PMN) and of HL-60 myeloid leukemia cells were analyzed with a panel of defined, monoclonal anti-carbohydrate antibodies. Antigenicities of intact PMN, HL-60, and retinoic acid-induced HL-60 (r.a.-HL-60) were studied by flow cytofluorometry.

Abstract:

Glycolipids are a large and heterogeneous family of sphingolipids that form complex patterns on eukaryotic cell surfaces. This molecular diversity is generated by only a few enzymes and is a paradigm of naturally occurring combinatorial synthesis. We report on the biosynthetic principles leading to this large molecular diversity and focus on sialic acid–containing glycolipids of the ganglio–series. These glycolipids are particularly concentrated in the plasma membrane of neuronal cells. Their de novo synthesis starts with the formation of the membrane anchor, ceramide, at the endoplasmic retic

We estimated glycolipids biochemically using a standard protocol in six different tissues.

Abstract:

In the same way that peptide antigens are presented by major histocompatibility complex (MHC) molecules, glycolipid antigens can also activate the immune response via binding to CD1 proteins on antigen-presenting cells (APCs) and stimulate CD1-restricted T cells. In humans, there are five members of the CD1 family, termed CD1a–e, of which CD1a–d are involved in glycolipid presentation at the cell surface, while CD1e is involved in the intracellular trafficking of glycolipid antigens. Both endogenous (self-derived) and exogenous (non-self-derived) glycolipids have been shown to bind to members

It is possible that this barrier might be augmented by topical application of pure glycolipid, which could diffuse through the regions between the squarnes.

Abstract:

A small fraction of the molecules internalized by endocytosis reaches the Golgi complex through a retrograde pathway that is poorly understood. In the present work, we used bacterial toxins to study the retrograde pathway in Vero cells. The recombinant B subunit of verotoxin 1B (VT1B) was labeled with fluorescein to monitor its progress within the cell by confocal microscopy. This toxin, which binds specifically to the glycolipid globotriaosyl ceramide, entered endosomes by both clathrin-dependent and -independent pathways, reaching the Golgi complex. Once internalized, the toxin-receptor comp

Abstract:

Glycolipids are a class of biodegradable biosurfactants that are non-toxic and based on renewables, making them a sustainable alternative to petrochemical surfactants. Enzymatic synthesis allows a tailor-made production of these versatile compounds using sugar and fatty acid building blocks with rationalized structures for targeted applications. Therefore, glycolipids can be comprehensively designed to outcompete conventional surfactants regarding their physicochemical properties. However, enzymatic glycolipid processes are struggling with both sugars and fatty acid solubilities in reaction me

ABSTRACT Immune evasion is required for Mycobacterium tuberculosis to survive in the face of robust adaptive CD4+ T-cell responses. We have previously shown that M. tuberculosis can indirectly inhibit CD4+ T cells by suppressing the major histocompatibility complex class II antigen-presenting cell function of macrophages. This study was undertaken to determine if M. tuberculosis could directly inhibit CD4+ T-cell activation. Murine CD4+ T cells were purified from spleens by negative immunoaffinity selection followed by flow sorting. Purified CD4+ T cells were activated for 16 to 48 h with CD3

Abstract To identify surface Ag uniquely expressed on human germinal center B cells, we produced a mouse mAb, HJ6.

HJ6 did not label mononuclear cells from peripheral blood, splenocytes, and any of 29 cell lines including 23 B cell lines. This binding pattern of HJ6 was very similar to that of a mAb named 5B5. It was shown previously that 5B5 bound a glycolipid named CTH (CD77) and its Ag was expressed on HK23- PNA+ tonsillar lymphocytes and Burkitt's lymphoma cell l

Photopolymerizable glycolipids incorporating ceramide- or amido-type linkers and able to form stable monolayers were efficiently synthesized by chemical and enzymatic methods. Glycolipid polymer films served as platforms for the immobilization of proteins through specific carbohydrate–protein interactions at the air–water interface. Carbohydrate-binding proteins deposited on the glycolipid film were observed by atomic force microscopy, which showed varying submicron-sized protein patterns such as dendrites, dots, and networks, depending on the lipid structure, membrane preparation process, and

Abstract:

Glycolipids are non-ionic surfactants occurring in numerous products of daily life. Due to their surface-activity, emulsifying properties, and foaming abilities, they can be applied in food, cosmetics, and pharmaceuticals. Enzymatic synthesis of glycolipids based on carbohydrates and free fatty acids or esters is often catalyzed using certain acyltransferases in reaction media of low water activity, e.g., organic solvents or notably Deep Eutectic Systems (DESs). Existing reports describing integrated processes for glycolipid production from renewables use many reaction steps, therefore this st

Glycolipids are the components of cellular membrane containing glycan and lipid parts. Transport of glycolipids from membrane and vice versa from extracellular space into the membrane is possible. This opens opportunity for modification of cellular membrane via embedding of glycolipids. In practice, synthetical analogs of glycolipids are significantly more convenient than natural glycolipids for such application, as the properties of the synthetical analogs can be varied and other bioactive components besides glycans can be introduced into their structure.

Furthermore, indirect immunofluorescence demonstrates that Hsp70 proteins are surface exposed in H. influenzae only after heat shock and are contained in the outer membrane protein fractions.

However, the targets of these antibodies and the kinetics of their production are not known. Several groups have attempted, without success, to identify surface proteins on the amastigote form of the parasite to which IgG can bind.
