Over-expression of paneth cell-derived anti-microbial peptides in the gut of patients with ankylosing spondylitis and subclinical intestinal inflamma…
2010
OBJECTIVES: Subclinical gut inflammation has been demonstrated in patients with AS. Altered expression of paneth cell (PC) anti-microbial peptides have been reported in the inflamed ileum of patients with Crohn's disease (CD). Here, we investigated the expression of PC-derived peptides in subclinical gut inflammation in AS. METHODS: Multiple adjacent mucosal biopsies from terminal ileum were obtained from 25 patients with AS, 30 CD and 15 healthy controls (HCs). Expression of human α-defensin 5 (HD-5), phospholipase A2 (PLA2), lysozyme and SOX-9 molecules was assessed by quantitative Taqman RT-PCR on mucosal samples. Immunohistochemistry with anti-human HD-5 antibody and genotyping of relev…
Relationship between Bone Marrow PD-1 and PD-L1 Expression and the Presence of Osteolytic Bone Disease in Multiple Myeloma Patients
2018
Abstract Alterations of the bone marrow (BM) immune-microenvironment characterize the progression of monoclonal gammopathies and the development of osteolytic bone disease in multiple myeloma (MM). MM patients exhibit immune dysfunctions as impaired dendritic, NK and T cells, whereas the onset of MM osteolytic lesions is associated to an increased prevalence of Th17 cells. Recently, the pathophysiological role of the programmed cell death protein 1 (PD-1)/PD-1 ligand (PD-L1) pathway together with an increase of myeloid derived suppressor cells (MDSCs) in the induction of tumor tolerance and immune evasion has been underlined with a therapeutic relevance. However, unclear data on the express…
