UNLABELLED The liver, a unique tolerogenic organ, is regarded as the site to trap and destroy aging erythrocytes and activated T cells. However, to date, the mechanisms for why the liver is tolerogenic and whether liver Kupffer cells (KC) are critical phagocytes for apoptotic cells (AC) contributing to the liver immunosuppression remain unclear. Here we report that KC is the main phagocyte for ...

Drug induced liver injury (DILI) is an idiosyncratic adverse drug reaction leading to severe liver damage. Kupffer cells (KC) sense hepatic tissue stress/damage and therefore could be a tool for the estimation of consequent effects associated with DILI. Aim of the present study was to establish a human in vitro liver model for the investigation of immune-mediated signaling in the pathogenesis o...

Keratinocytes (KC) are important source of and targets for several cytokines. Although KC express IL-15 mRNA, the functional effects of IL-15 on these epithelial cells remain to be dissected. Investigating primary human foreskin KC and HaCaT cells, we show here by semiquantitative RT-PCR and flow cytometric analysis that both translate IL-15 and IL-15R mRNA and express IL-15 and IL-15Ralpha pro...

Heat-killed whole BCG cells (KC) and BCG cell walls (CW) were each tested in emulsified form for their potency to cause regression of a transplanted guinea pig hepatoma. On a weight basis, KC were at least as effective as CW in causing tumor regression and elimination of microscopic lymph node metastasis, and they, as well as purified protein derivative of mycobacteria, provoked delayed cutaneo...

Background: It is now well established that several environmental stress factors cause activation of p38 MAP kinase and JNK in various cell types to produce chemokines. Objective: To investigate the expression of CXC chemokines Gro/KC and SDF- 1a in rat's H4 hepatoma cells in response to heat shock, hyperosmolarity and oxidative stress. Methods: Hepatoma cells were maintained in MEM medium. Cel...

Accurate estimation of crop evapotranspiration (ETc) is important to determine water requirements in greenhouse agriculture and improve the irrigation use efficiency. Here, a 3-year (2017–2019) experiment with spring greenhouse-grown eggplant (Solanum melongena L.) was conducted investigate variation coefficient (Kc) measured weighing lysimeter, adjust Kc based on local climate (Kc,Adj), estima...

Keratoconus (KC) is a corneal disease associated with structural abnormalities in the corneal epithelium, Bowman's layer and stroma and altered concentration of tear components. KC corneas show a different pattern of collagen lamellae than their normal counterparts. Also, a reduction of several collagen types in KC epithelium and stroma was observed. Altered expression and/or activity of lysyl ...
