Transient Dimers of Allergens

BACKGROUND Allergen-mediated cross-linking of IgE antibodies bound to the FcepsilonRI receptors on the mast cell surface is the key feature of the type I allergy. If an allergen is a homodimer, its allergenicity is enhanced because it would only need one type of antibody, instead of two, for cross-linking. METHODOLOGY/PRINCIPAL FINDINGS An analysis of 55 crystal structures of allergens showed...

Formation of transient dimers by a retroviral protease.

Retroviral proteases have been shown previously to be only active as homodimers. They are essential to form the separate and active proteins from the viral precursors. Spumaretroviruses produce separate precursors for Gag and Pol, rather than a Gag and a Gag-Pol precursor. Nevertheless, processing of Pol into a PR (protease)-RT (reverse transcriptase) and integrase is essential in order to obta...

DFT study of dimers of dimethyl sulfoxide in gas phase

Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...

Photocleavage of coumarin dimers studied by femtosecond UV transient absorption spectroscopy.

Coumarins are a class of UV absorbing compounds which exhibit fast, photoinduced cyclobutane ring formation and cleavage reactions. The photophysics behind such processes hold significant relevance for biomedical and photoresponsive materials research. In order to further understand the underlying dynamics of the cleavage reaction, and develop strategies for increasing the reaction efficiency, ...

Are profilins relevant allergens or confusion allergens?

Advances in the techniques used to study allergic patients have allowed us to recognize multiple mistakes made in the past, and thus to avoid prescribing patient immunotherapy treatments that are not fully valid. One of the major achievements has been the molecular diagnosis of allergic diseases. In effect, while in the past we only had gross determinations of specific IgE to pollens, we can no...
