Fatty acids as haptens: exploring the limits of antigenicity

Fatty acids (FAs) are relatively small, hydrophobic and highly mobile molecular structures with vital biological functions and a ubiquitous distribution. Surprisingly, however, they can be rendered immunogenic. We have synthesised a novel immunogen in which dicarboxylic linoleic acid was conjugated to a carrier protein. Dicarboxylic fatty acids (DCA) differ from their normal counterparts only by their possession of a carboxyl group at each end of the molecule. When conjugated to proteins as haptens, they are, therefore, presented to the immune system with a free carboxyl group at the distal end, instead of a methyl group. Polyclonal IgG antibodies raised in response to this unique immunogen could bind not only conjugated hapten with high affinity, but also the equivalent free FA in mono and dicarboxylic form. Similar conjugates constructed from normal FAs produced much weaker antibody responses and could scarcely be considered antigenic at all. The cross-reactivities of the anti-DCA antibodies with FA variants differing in the number, position and configuration of their double bonds showed that the antibody paratope (binding site) was structured to accommodate the hapten in a way that depended on the precise shape of the acyl chain. We suggest that FAs become much more effective as B-cell epitopes when presented with their hydrophilic carboxyl group exposed on the surface of immunogenic conjugates. This type of epitope is determined by the particular double bond pattern of the unsaturated acyl chain, as well as the polar head group. (C) 2003 Elsevier Ltd. All rights reserved.

The temporal and spatial limits of compensation for fixational eye movements

High-fidelity eye tracking is combined with a perceptual grouping task to provide insight into the likely mechanisms underlying the compensation of retinal image motion caused by movement of the eyes. The experiments describe the covert detection of minute temporal and spatial offsets incorporated into a test stimulus. Analysis of eye motion on individual trials indicates that the temporal offset sensitivity is actually due to motion of the eye inducing artificial spatial offsets in the briefly presented stimuli. The results have strong implications for two popular models of compensation for fixational eye movements, namely efference copy and image-based models. If an efference copy model is assumed, the results place constraints on the spatial accuracy and source of compensation. If an image-based model is assumed then limitations are placed on the integration time window over which motion estimates are calculated. (c) 2006 Elsevier Ltd. All rights reserved.
