Hydrocortisone and 'macrocortin' inhibit the zymosan-induced release of lyso-PAF from rat peritoneal leucocytes.
No full textHydrocortisone and the glucocorticoid-induced anti-phospholipase protein macrocortin, were tested as inhibitors of PAF generation. The steroid produced a dose-dependent inhibition of the release of the PAF precursor 2-lyso-PAF, and this effect was mimicked by affinity-purified macrocortin. Neither agent had any effect on the acetylation of lyso-PAF to PAF. Of other drugs tested only phospholipase inhibitors blocked lyso-PAF release and sulphydryl reagents blocked the acetylation step. It is concluded that glucocorticoids inhibit the generation of PAF and this could be an important component of their anti-anaphylactic and anti-inflammatory action
Human recombinant lipocortin 1 inhibits prostacyclin production by human umbilical artery in vitro.
No full textSubmicromolar concentrations of human recombinant Lipocortin 1 inhibit the release of prostacyclin from human umbilical artery rings in a dose-dependent fashion. This is the first demonstration that the recombinant protein is effective in human cells
Flowers through insect eyes: the contribution of pollinator vision to the evolution of flower colour
No full textPhDFlowers’ colours are an essential element of their ability to attract visits from
pollinators. However, the colours as they appear to human observers can differ
substantially from their appearance to insect pollinators, and so it is essential to consider
pollinator vision in any study of the ecology of flower colour.
In this thesis I describe how I have overseen the development of an online database to
provide accurate information on floral spectral reflectance measured without human
observational bias. This resource allows a more accurate consideration of flower colours
in future studies, and permits investigations of flower colours within and across
habitats. Using the records in this database, I analysed flowers from two European
habitats for spatial or temporal changes, modelling the colours according to insect visual
perception. I discovered that the insect-colour composition of the plant communities
does not change either along an altitudinal gradient or throughout the year. These novel
and ecologically-relevant analyses contradict previous observational studies, but support
the theory of a pollination “market” in which flowers compete for pollinator visitation.
I then describe my experimental investigations into the visual capabilities of two
pollinators and how this may relate to what colours of flowers they visit. Firstly I study
the foraging behaviour of bees under spatially inconsistent illumination and how this
impacts on their choice behaviour. I revealed patchy light can have measurable effects
on bee foraging behaviour: they intentionally choose familiar over unfamiliar
illumination, which may impact on the flowers they visit in complex natural
environments. Secondly, I detail the new evidence for a red-sensitive photoreceptor in
South African monkey beetles, a major pollinator in a habitat containing many longwavelength-
reflecting flowers, which are not classically “attractive” to bees.
Throughout this thesis, I explore how pollinator vision has shaped the evolution of
flower colours in different contexts.Biotechnology and Biological Science Research Council.
