Prevalence and treatment patterns of adult atopic dermatitis in the UK Clinical Practice Research Datalink.

The prevalence of active atopic dermatitis (AD) in adults in the UK according to disease severity shows variability. This study evaluated disease prevalence and treatment patterns among the adult UK population with AD. Data were obtained from the Clinical Practice Research Datalink (CPRD) database.

Galectin-3: A Positive Regulator of Leukocyte Recruitment in the Inflamed Microcirculation.

In vivo and ex vivo imaging were used to investigate the function of galectin-3 (Gal-3) during the process of leukocyte recruitment to the inflamed microcirculation. The cremasteric microcirculation of wild-type (C57BL/6), Gal-3, and CXCR1 mice were assessed by intravital microscopy after PBS, IL-1β, TNF-α, or recombinant Gal-3 treatment. These cellular responses were investigated further using flow-chamber assays, confocal microscopy, flow cytometry, PCR analysis, and proteome array.

The impact of environmental enrichment on the murine inflammatory immune response.

Living in a mentally and physically stimulating environment has been suggested to have a beneficial effect on the immune response. This study investigates these effects, utilizing a 2-week program of environmental enrichment (EE) and 2 models of acute inflammation: zymosan-induced peritonitis (ZIP) and the cecal ligation and puncture (CLP) model of sepsis. Our results revealed that following exposure to EE, mice possessed a significantly higher circulating neutrophil to lymphocyte ratio compared with control animals.

Methods for assessing the effects of galectins on leukocyte trafficking.

Numerous protocols exist for investigating leukocyte recruitment both in vitro and in vivo. Here we describe three of these methods; an in vitro flow chamber assay, intravital microscopy, and zymosan-induced peritonitis, and give details as to how they can be used to study the actions of galectins on this crucial process.

Endogenous galectin-1 exerts tonic inhibition on experimental arthritis.

Little is known about the role(s) of endogenous galectin-1 (Gal-1) in arthritis. In this study we queried whether antiarthritic functions for this effector of endogenous anti-inflammation could be unveiled by studying collagen-induced arthritis in Gal-1(-/-) mice. Gal-1(-/-) and C57BL/6J [wild-type (WT)] mice received an immunization of chicken type II collagen (CII) in CFA followed by a booster on day 21, which consisted of CII in IFA.

Loss of substance P and inflammation precede delayed neurodegeneration in the substantia nigra after cerebral ischemia.

Focal cerebral ischemia leads to delayed neurodegeneration in remote brain regions. The substantia nigra (SN) does not normally show primary neuronal death after ischemic events affecting the striatum, but can exhibit delayed neuronal loss after the ischemic injury through mechanisms that are unknown. No data are available in mice showing acute post-stroke inflammation and remote injury in the SN.

The effect of galectins on leukocyte trafficking in inflammation: sweet or sour?

The trafficking of leukocytes from the blood stream to the surrounding tissue is a fundamental feature of an inflammatory response. Although many of the adhesion molecules and chemokines that direct leukocyte trafficking have been identified, there is still much to be discovered, particularly with regard to the persistence of leukocyte infiltrates in chronic inflammation. Elucidating the molecular mechanisms involved in this process is critical to understanding and treating inflammatory pathologies.
