Background Lipopolysaccharide (LPS) is widely recognized as a potent activator of monocytes/macrophages, and its effects include an altered production of key mediators, such as inflammatory cytokines and chemokines. The involvement of Gi protein in mediating LPS effects has been demonstrated in murine macrophages and various cell types of human origin. Purpose The aim of the present work was ...

Purpose The purpose of this study was to investigate the role of substance P (SP) in patients affected with corneal neovascularization (CNV) and in three different Tac1-knockout (KO) murine models of CNV. Methods SP levels in tears were measured with a multiplex bead assay. The extent of human CNV was quantified as number of affected corneal quadrants. Murine CNV was induced in both strains b...

To better understand the ecology of the poultry gastrointestinal (GI) microbiome and its interactions with the host, we compared GI bacterial communities by sample type (fecal or cecal), time (1, 3, and 6 weeks posthatch), and experimental pen (1, 2, 3, or 4), and measured cecal mRNA transcription of the cytokines IL18, IL1β, and IL6, IL10, and TGF-β4. The microbiome was characterized by sequen...

BACKGROUND TH1 cytokines, such as IFNγ and TNFα, and potentially innate cytokines, such as IL6, can potentiate the immune response to tumor. Cytokines, such as IL1β, IL8, and IL10, may suppress anticancer immunity. Thus, we prospectively evaluated the association between peripheral-cytokine concentrations and prostate cancer. METHODS We conducted an age-race matched case-control study (268 pa...

Introduction Although all patients with chronic inflammatory conditions are at risk for developing type AA amyloidosis, the incidence varies widely between the different Autoinflammatory syndromes. The reported incidence is about 35% of patients with CAPS (cryopyrin-associated periodic syndrome) which comprises familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome and CINCA (chr...
