Differential requirements for the processing and presentation of soluble and particulate bacterial antigens by macrophages

The requirements for antigen processing and presentation by macrophages using various forms of antigens derived from Listeria monocytogenes have been studied. Antigen presentation was monitored by T cell-macrophage binding and interleukin production using T cells from Listeria monocytogenes-infected mice and specific T cell hybridomas. Antigen processing requirements were defined by three criteria: (a) inhibition by lysosomotropic agents, NH4Cl and chloroquine; (b) kinetic relationships between antigen uptake and antigen presentation; and (c) antigen presentation by macrophages pre-fixed with glutaraldehyde. In comparing heat-killed Listeria monocytogenes (HKLM) with soluble listerial proteins (SLP), the presentation of SLP was less sensitive to lysosomotropic agents, showed faster antigen processing kinetics than with HKLM and could occur using pre-fixed macrophages. Transitions between particulate and soluble forms had dramatic influences on processing requirements. Antigens associated with HKLM could be converted to soluble forms which did not require processing by preculture with macrophages and also by physical (e.g. sonication) and chemical (sodium dodecyl sulfate) treatments in the presence of protease inhibitors. Conversely, antigen processing was required when SLP were converted to a particulate form by covalent binding to latex beads. Analysis of SLP by molecular sieve chromatography and preparative SDS-polyacrylamide gel electrophoresis revealed that high molecular weight proteins (greater than 60 kDa) could be presented by prefixed macrophages without prior processing. We conclude that the transition from a particulate to soluble antigenic form can be a significant antigen processing event.

“…As attempts to get product, even as mixtures, were unsuccessful, alteration of the protective group after its installation became the strategy. For this, pyruvylation of the 4,6-diol [20][21][22] seemed a perfect model system, as the obtained equatorial (thermodynamic product) ester moiety easily can be functionalized with e.g. C-nucleophiles to give bulky tertiary alcohols.…”

Conformational Distortion Using a Molecular Lever: Synthesis and Conformational Studies of Galactoside Derivatives

Novel bicyclic d‐galactose derivatives containing a molecular lever were synthesized and their conformations studied by 1H‐NMR and crystallography. Increasing the bulkiness in the alkylidene ring in combination with introducing bulky O‐protective groups on the pyranoside ring, causes a ring flip from a 4C1 into the axial rich 1C4 conformation. With less bulky protective groups, the pyranoside ring resides in the 4C1 conformation despite distortion of the external alkylidene ring.

“…The occurrence of crazing in opaque materials has been demon6trated by increased retention of pigments at the intersection of the craze with the surface. 16 The very rapid initial growth of crazes may be the reason that the existence of a minimum craze length has been postulated." The initial growth rate was perhaps too fast to allow observation of crazes shorter than the minimum.…”

Stress crazing of transparent plastics. Computed stresses at a nonvoid craze mark

synopsisThe mechanism of the stress crazing of transparent plastics is discussed in terms of a model suggested by recent publications in which the interior of the craze mark contains tenacious, elongated fibrils connecting the parallel faces. Internal and external stress distributions have been computed for a two-dimensional model of equilibrium crazes. Three shape parameters are used; the length of a uniform section, the thickness of the uniform section, and the length of a tapered tip section. The configuration of the tapered tip is determined in the model by the requirement that stresses remain finite. Strtbilization of the craze is attributed to reduction of stress intensity by an increase in the ratio of tip length to thickness as the craze propagates. Two conditions are noted where craze stability is not predicted. Qualitative agreement was found between the model and growth kinetics reported in the literature, but the simple equilibrium model does not provide a basis for explaining the effects of stress level and temperature on the size of craze marks. The occurrence of crazing rather than general elongation is explained in this model by the stress intensification which occurs when the fibrils of the craze material are elongated. 1845
