While treating sepsis, bacterial clearance must be achieved to ensure patient survival, and the hepatic immune response is responsible for this process. In particular, Kupffer cells play a crucial role in the hepatic immune response against infectious agents. Recently, two populations of Kupffer cells have been described liver-resident macrophages (Mϕ) (F4/80+ CD11b- CD68+ cells) and hepatic Mϕ derived from circulating monocytes (F4/80+ CD11b+ CD68- cells). We examined the properties of both types of hepatic Mϕ obtained from irradiated and normal mice and their role in sepsis. Hepatic F4/80+ CD11b- CD68+ cells from both normal and irradiated mice did not show any antibacterial activity. However, F4/80+ CD11b+ CD68- cells from normal mice behaved as effector cells against sepsis by Enterococcus faecalis, although those from irradiated mice lost this ability. Moreover, hepatic F4/80+ CD11b+ CD68- cells from normal infected mice were shown to be IL-12+ IL-10- CD206- CCL1- (considered M1Mϕ), and hepatic F4/80+ CD11b- CD68+ cells from the same mice were shown to be IL-12- IL-10+ CD206+ CCL1- (considered M2aMϕ). When normal mice were exposed to radiation, hepatic F4/80+ CD11b+ CD68- cells altered their phenotype to IL-12- IL-10+ CD206- CCL1+ (considered M2bMϕ), independent of infection, but hepatic F4/80+ CD11b- CD68+ cells remained IL-12- IL-10+ CD206+ CCL1- (M2aMϕ). In addition, hepatic F4/80+ CD11b+ CD68- cells from irradiated mice acquired antibacterial activity upon treatment with CCL1 antisense oligodeoxynucleotides. Therefore, the characteristics of hepatic F4/80+ CD11b+ CD68- cells play a key role in the antibacterial response against gut-associated sepsis.

Previous studies showed that natural killer (NK) cells mediate contact hypersensitivity (CHS) reaction. Many reports are showing that obesity promotes several inflammatory diseases. It was shown that diet-induced obesity (DIO) aggravates classical T cell-mediated CHS in mice.

To determine whether the high-fat diet (HFD)-induced obesity modulates antigen-specific NK cell-mediated response.

We evaluated the effect of DIO on NK cell-mediated CHS reaction using a model of dinitrofluorobenzene (DNFB)-induced CHS in Rag1

mice.

Rag1

mice fed HFD for 8 but not for 4 weeks developed aggravated CHS reaction determined by ear swelling measurement when compared to animals kept on normal diet (ND) prior to DNFB sensitization. The obese Rag1

mice presented the adipose tissue inflammation. Furthermore, in vitro analysis showed that feeding with HFD significantly increases interferon γ (IFN-γ) and interleukin (IL)-12p70 and decreases adiponectin concentration in liver mononuclear cell (LMNC) culture supernatant natural killer (NK) cells. DIO aggravates NK cell-mediated contact hypersensitivity (CHS) in Rag1-/- mice.

Uncertainty remains about the best route and timing of medical nutrition therapy in the acute phase of critical illness. Early combined enteral nutrition (EN) and parenteral nutrition (PN) may represent an attractive option to achieve recommended energy and protein goals in select patient groups. This meta-analysis aims to update and summarize the current evidence.

This systematic review and meta-analysis includes randomized controlled trials (RCTs) targeting the effect of EN alone vs a combination of EN with PN in the acute phase of critical illness in adult patients. Assessed outcomes include mortality, intensive care unit (ICU) and hospital length of stay (LOS), ventilation days, infectious complications, physical recovery, and quality-of-life outcomes.

Twelve RCTs with 5543 patients were included. Treatment with a combination of EN with PN led to increased delivery of macronutrients. No statistically significant effect of a combination of EN with PN vs EN alone on any of the parameters was observed mortality (risk ratio = 1.0; 95% CI, 0.79-1.28; P= .99), hospital LOS (mean difference, -1.44; CI,-5.59 to 2.71; P =.50), ICU LOS, and ventilation days. Trends toward improved physical outcomes were observed in two of four trials.

A combination of EN with PN improved nutrition intake in the acute phase of critical illness in adults and was not inferior regarding the patients' outcomes. Large, adequately designed trials in select patient groups are needed to answer the question of whether this nutrition strategy has a clinically relevant treatment effect.

Keloid lesions are characterized by mesenchymal cell proliferation and excessive extracellular matrix deposition. Previous microarray analyses have been performed to investigate the mechanism of keloid development. However, the molecular pathology that contributes to keloid development remains obscure.

Exploring the underlying essential molecules of keloids using microarrays.

We performed microarray analyses of keloid and non-lesional skin tissues both in vivo and in vitro. Gene expression levels were compared between tissues and cells. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and immunopathological staining were used to determine the expression levels of molecules of interest in keloid tissues.

Several common molecules were upregulated in both keloid tissues and keloid-lesional fibroblasts. PTPRD and NTM were upregulated both in vivo and in vitro. selleck MDFI and ITGA4 were located at the center of the gene co-expression network analysis using keloid tissuess. qRT-PCR revealed significant expression levels of PTPRD and MDFI in keloid tissues. Immunopathological staining revealed that MDFI-positive cells, which have fibroblast characteristics, were located in the keloid-associated lymphoid tissue (KALT) portion of the keloid tissue.

Our gene expression profiles of keloids distinguished the difference between lesional tissue and cultured lesional fibroblasts, and MDFI was commonly expressed in both tissues and cells. Thus, MDFI-positive cells, which were located in the KALT, might be used in in vitro keloid studies and may play an important role in keloid pathogenesis.
