Toll-like receptor 4–, 7–, and 8–activated myeloid cells from patients with X-linked agammaglobulinemia produce enhanced inflammatory cytokines

Background: Bruton tyrosine kinase (BTK) is a component of signaling pathways downstream from Toll-like receptors (TLRs) 2, 4, 7, 8, and 9. Previous work in BTK-deficient mice, cell lines, and cultured cells from patients with X-linked agammaglobulinemia (XLA) suggested defective TLR-driven cytokine production...

Three novel alleles at HLA-DRB1 locus identified by Sequence Based Typing

We describe here the sequences of 3 HLA-DRB1 new variants officially named DRB1*03:05:03, DRB1*11:10:02, DRB1*14:86. These novel alleles have been detected in three Caucasoid individuals by sequence-based typing (SBT). The first allele and the second one are the result of a silent mutation, which does not imply any..

The stimulation of an osteogenic response by classical monocyte activation.

The monocyte/macrophage system plays a central role in host defense, wound healing and immune regulation at biomaterial surfaces. Monocytes can be classically and alternatively activated, and can be stimulated differently in response to variations in biomaterial surface properties. In this study, human monocytes,..

Proteomic analysis of psoriatic skin tissue for identification of differentially expressed proteins: Up-regulation of GSTP1, SFN and PRDX2 in psoriatic skin

Proteomic analysis of psoriatic skin tissue for identification of differentially expressed proteins: Up-regulation of GSTP1, SFN and PRDX2 in psoriatic skin

Psoriasis is a chronic inflammatory skin disease, characterized by a combination of abnormal proliferation of keratinocytes, immunology and vascular proliferation. Proteomic analyses have revealed some clues regarding the pathogenesis of psoriasis. In the present study, we conducted an investigation of different..

C-reactive protein (CRP): An important diagnostic and prognostic tool in nursing-home-associated pneumonia

Pneumonia is the second most common infection in long term care (LTC) residents and is a leading cause of death from infection in those groups of patients. Atypical presentations and fewer presenting signs and symptoms in older patients complicate diagnosis and delay initiation of adequate treatment. The aim of this..
