Latex allergy: the sum quantity of four major allergens shows the allergenic potential of medical gloves
2007
Background: Assessment of allergenic potential of medical devices made of natural rubber latex (NRL) requires the measurement of concentrations of specific allergenic proteins or polypeptides eluting from rubber. Methods: Four NRL allergens (Hev b 1, 3, 5, and 6.02) were quantified in all medical glove brands marketed in Finland in 1999, 2001, and 2003 (n = 208) by a capture enzyme immunoassay. The results were compared with those obtained from previous nationwide market surveys, using a skin prick test-validated human IgE-based ELISA-inhibition method. Results: A high overall correlation (r = 0.87, 95% CI 0.83–0.90) emerged between the sum values of the four allergens(μg/g glove) and Ig…

The CMS4 mesenchymal subtype of colorectal cancer (CRC) is associated with poor prognosis and resistance to treatment. The cellular prion protein PrPC is overexpressed in CMS4 tumors and controls the expression of a panel of CMS4-specific genes in CRC cell lines. Here, we sought to investigate PrPC downstream pathways that may underlie its role in CMS4 CRC. By combining gene set enrichment analyses and gain and loss of function approaches in CRC cell lines, we identify the integrin-linked kinase ILK as a proximal effector of PrPC that mediates its control on the CMS4 phenotype. We further leveraged three independent large CRC cohorts to assess correlations in gene expression pattern with pa…
Alternative NF-κB signaling regulates mTEC differentiation from podoplanin-expressing precursors in the cortico-medullary junction

The thymic epithelium forms specialized niches to enable thymocyte differentiation. While the common epithelial progenitor of medullary and cortical thymic epithelial cells (mTECs and cTECs) is well defined, early stages of mTEC lineage specification have remained elusive. Here, we utilized in vivo targeting of mTECs to resolve their differentiation pathways and to determine whether mTEC progenitors participate in thymocyte education. We found that mTECs descend from a lineage committed, podoplanin (PDPN)-expressing progenitor located at the cortico-medullary junction. PDPN(+) junctional TECs (jTECs) represent a distinct TEC population that builds the thymic medulla, but only partially supp…

Prior studies demonstrate that adenosine, acting at one or more of its receptors, mediates the anti-inflammatory effects of methotrexate in animal models of both acute and chronic inflammation. Both adenosine A2A and A3 receptors contribute to the anti-inflammatory effects of methotrexate treatment in the air pouch model of inflammation, and the regulation of inflammation by these two receptors differs at the cellular level. Because different factors may regulate inflammation at different sites we examined the effect of low-dose weekly methotrexate treatment (0.75 mg/kg/week) in a model of acute peritoneal inflammation in adenosine A2A receptor knockout mice and A3 receptor knockout mice an…
