These cells are capable of phagocytosis, which is considered to be essential for their regulatory function. In addition, there is a strong expression of the gap junction protein connexin43 (Cx43) in the TM. Here, we investigated functional relationships between phagocytosis activity of TM cells and their expression of Cx43. Phagocytosis was measured by showing the ability of TM cells to engulf inert fluorescent particles consisting of pHrodo. We found that internalized pHrodo was partially co-localized with Cx43 and that the phagocytic activity was dramatically reduced after knockdown of Cx43 using lentiviral Cx43 shRNA. These results suggest that Cx43 is involved in the regulation of phagocytosis by TM cells.

Stem cells derived hepatocyte-like cells (HLCs) attenuated liver injury upon transplantation in animal models for liver fibrosis. However, only a small portion of the transplanted cells propagated in the recipient liver. AIM We hypothesized that the efficiency of cell therapy could be improved by transplanting amniotic mesenchymal stem cells (AMSCs) derived HLCs along with human umbilical vein endothelial cells (HUVECs) and undifferentiated AMSCs. METHODS Briefly, we used a two-step protocol to generate induced HLCs. We confirmed organoids formation of HLCs in 3D collagen scaffolds with HUVECs and AMSCs. To determine whether the HLCs can migrate into the liver tissue and perform in vivo function, we transplanted the cells to mice with liver fibrosis. RESULTS Co-culture of HLCs with HUVECs and AMSCs demonstrated improved function of HLCs within the organoids. Furthermore, transplantation using non-homogeneous cells, i.e. HLCs mixed with HUVECs and AMSCs, exhibited better graft survival in the host animals with liver fibrosis. Our experiment results suggested that compared to mock transplantation or HLCs transplantation groups, liver fibrosis was reduced significantly in mixed-cell groups. The AST levels in the plasma of transplanted mice were markedly decreased only in the mixed-cell transplantation group. The engraftment of HLCs in mice liver was better in mixed-cell transplantation group, compared with HLCs-only transplantation group. CONCLUSIONS The HLCs attenuated liver fibrosis more efficiently when transplanted along with HUVECs and AMSCs, and this suggested that we could improve the efficiency of cell therapy by transplanting functional cells partially along with stromal cells.

The aqueous humor, produced by the ciliary body, passes into the anterior chamber of the eye and is filtered by the trabecular meshwork (TM), a tiny tissue found in the angle of the eye. This tissue, along with Schlemm's canal (SC) inner wall cells, is thought to control intraocular pressure (IOP) homeostasis for normal, optimal vision. The actin cytoskeleton of the tissue plays a regulatory role in maintaining IOP. One of the key risk factors for primary open angle glaucoma is persistent elevation of IOP, which compromises the optic nerve. The ZO-1 (Zonula Occludens-1), extracellular matrix protein integrins, and gap junction protein connexin43 (Cx43) are widely expressed in many different cell populations. Here, we investigated the localization and interactions of ZO-1, α3 integrin, β1 integrin, and Cx43 in cultured porcine TM and SC cells using RT-PCR, western immunoblotting and immunofluorescence labeling with confocal microscopy, along with co-immunoprecipitation. ZO-1 partially co-localized with α3 integrin, but not with β1 integrin, and co-immunoprecipitated with Cx43, as well as with α3 integrin. The association of ZO-1 with α3 integrin and Cx43 suggests that these proteins may form a multiple protein complex in porcine TM and SC cells. Since integrins interact with the actin cytoskeleton via scaffolding proteins, these results implicate junctional and scaffolding protein ZO-1 as a potential control point in regulation of IOP to normal levels for glaucoma therapy.

A previous study showed that altered miR-203 expression may provide highly diagnostic for systemic lupus erythematosus. However, whether miR-203 is a diagnostic biomarker for LN is still unknown. In the present research, serum samples from 35 cases of active LN patients, 58 cases of inactive LN patients, and 74 cases of healthy volunteers were collected to analyze the expression profiles of miR-203 by qRT-PCR. The serum concentration of complement component 3 (C3) and complement component 4 (C4) was detected using nephelometry method. The expression of inflammatory cytokines, including interleukin 1 beta (IL-1β), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α), were analyzed using enzyme-linked immunosorbent assay (ELISA). The effect of miR-203 overexpression on the TNF receptor associated factor 6 (TRAF6)-induced inflammation of human renal mesaIn summary, decreased circulating miR-203 might be a candidate diagnostic biomarker for human active LN, and it attenuated IL-β, IL-6, and TNF-α activation in TRAF6-treated HRMCs and HK-2 cells.

The "microinflammation state" is closely related to accelerated mortality in patients with chronic kidney disease (CKD). The aim of this study was to investigate the relationship between microinflammation and macrophage polarization in CKD. Tofacitinib The levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in peripheral blood of 30 non-dialysis CKD-5 patients (CKD group) and 20 healthy subjects (Con group) were measured. Peripheral mononuclear cells (PBMC) of each group were obtained, induced to differentiate into mature macrophages, and the expression of CD206 on the surface of macrophage M2 was detected. The expression of IL-10, TGF-β1 and TNF-α in the supernatant of macrophage culture medium was detected by real time RCR and ELISA. We found that the levels of hs-CRP, IL-6 and TNF-α in peripheral blood of patients with CKD were significantly higher than those of the control group.
