BACKGROUND: Sepsis delays wound re-epithelialization. In this study we explored the effect of human sepsis sera as well as the effects of cytokines, growth factors and exosomes of sepsis sera treated normal fibroblasts (NF) on keratinocyte migration and proliferation in vitro. METHODS: Serum samples were taken on days 1, 4, and 9 from 44 patients diagnosed with severe sepsis, and from 14 matching healthy controls. We evaluated the effects of sepsis serum with or without TNF-α, EGF, EGF receptor inhibitor or exosomes of sepsis sera treated NF on human keratinocyte (HaCaT) proliferation (BrdU assay), viability (MTT assay), and migration (horizontal wound healing model)...

PURPOSE: To characterize the immunologic profile in aqueous humor (AqH) of HIV-infected individuals with cytomegalovirus retinitis (CMVr) or ocular syphilis and to assess if AqH and plasma represent independent cytokine compartments. METHODS: Concentrations of 27 cytokines in AqH and plasma of HIV-infected individuals with CMVr (n = 23) or ocular syphilis (n = 16) were measured by multiplex assay. Cytokine profiles of both groups were compared. RESULTS: Individuals with CMVr had higher plasma concentrations of interleukin (IL)-7, IL-8, IL-10, interferon (IFN)-γ, IFN-α2, G-CSF, IP-10 and IL-1α; as well as higher AqH concentrations of IL-1α, IP-10 and GM-CSF than those with ocular syphilis...

Inflammatory cytokines are potential modulators of infarct progression in acute ischaemic stroke, and are therefore possible targets for future treatment strategies. Cytokine studies in animal models of surgically induced stroke may, however, be influenced by the fact that the surgical intervention itself contributes towards the cytokine response. Community-dwelling domestic dogs suffer from spontaneous ischaemic stroke, and therefore, offer the opportunity to study the cytokine response in a noninvasive set-up...

BACKGROUND:  Dengue virus infection typically causes mild dengue fever, but, in severe cases, life-threatening dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) occur. The pathophysiological hallmark of DHF and DSS is plasma leakage that leads to enhanced vascular permeability, likely due to a cytokine storm. METHODS:  Ninety patients with dengue during 2010-2012 in Singapore were prospectively recruited and stratified according to their disease phase, primary and secondary infection status, and disease severity, measured by plasma leakage...

BACKGROUND: Toll-like receptor (TLR)-mediated inflammation may contribute to neonatal sepsis, for which pentoxifylline (PTX), a phosphodiesterase inhibitor that raises intracellular cAMP, is a candidate adjunctive therapy. We characterized the anti-inflammatory effects of PTX towards TLR-mediated production of inflammatory (TNF, IL-1ß) and pro-resolution (IL-6, IL- 10) cytokines in human newborn and adult blood. METHODS: Newborn cord and adult blood were treated with PTX (50 - 400 μM) before, during or after stimulation with LPS (TLR4 agonist), R848 (TLR7/8 agonist) or LPS/ATP (inflammasome activation)...

We evaluated different lymphocyte populations and levels of plasma cytokines in peripheral blood as well as inflammatory infiltration and expressions of cytokines in lung tissues derived from macaque under long-term stimulated microgravity through being suspended in an antiorthostatic position so as to identify relevant immune parameters and to understand potential mechanisms of lung injury. Fifteen healthy male rhesus macaques were randomly divided into groups 1 (control, n = 5), groups 2 (head-down tilting for 6 weeks, n = 5), and groups 3 (head-down tilting for 6 weeks and recovery for 4 weeks, n = 5)...

Degenerative joint disease is common in cats, with signs of pain frequently found on orthopedic examination and radiographs often showing evidence of disease. However, understanding of the pathophysiology of degenerative joint disease and associated pain remains limited. Several cytokines have been identified as having a role in pain in humans, but this has not been investigated in cats. The present study was performed to use a multiplex platform to evaluate the concentration of 19 cytokines and chemokines in serum samples obtained from cats with and without degenerative joint disease and associated pain...

T lymphocytes are believed to play an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD). How T cells are recruited to the lungs and contribute to the inflammatory process is largely unknown. COPD is a heterogeneous disease, and discriminating disease phenotypes based on distinct molecular and cellular pathways may provide new approaches for individualized diagnosis and therapies. Bronchoalveolar lavage (BAL) and blood samples were obtained from 40 never-smokers, 40 smokers with normal lung function, and 38 COPD patients...

Cytokines expression can be influenced by polymorphisms in their respective coding genes. We associated the CTI/TTD haplotype (Hap-1) and TCI/CCI haplotype (Hap-2) in the IL4 gene formed by the -590, +33 and variable number of tandem repeat polymorphisms with the severity of chronic periodontitis in humans. The functionality of these IL4 haplotypes in the response of immune cells to phorbol 12-myristate 13-acetate (PMA) with Ionomycin and IL-1β (as inflammatory stimuli) was evaluated. Gene expression (quantitative real-time PCR), profile of secreted cytokines (multiplex) and phenotypic polarization of T cells (flow cytometry) were the outcomes assessed...

Gastroduodenitis caused by H. pylori, often acquired in early childhood, is found in about 50% of the adult population. Although H. pylori infections can remain asymptomatic, its virulence factors usually trigger epithelial vacuolization and degeneration, loss of microvilli, disintegration of cytoplasm, and leukocyte accumulation. It is believed that leukocyte infiltration is driven by cytokines produced locally in infected tissue. However, so far little is known about changes in serum cytokines in juvenile patients infected with H...

The long-term success of lung transplantation (LT) is limited by chronic lung allograft dysfunction (CLAD). Different phenotypes of CLAD have been described, such as bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS). The purpose of this study was to investigate levels of cytokines and chemokines in bronchoalveolar lavage fluid (BALF) as markers of these CLAD phenotypes. BALF was collected from 51 recipients who underwent (bilateral and unilateral) LT. The study population was divided into three groups: stable (ST), BOS, and RAS...
