Objective To investigate the molecular mechanism for change in permeability in brain microvascular endothelial cells (bEnd.3) induced by lipopolysaccharide (LPS). Methods Monolayers of bEnd.3 were exposed to LPS,in the presence or absence of exoenzyme C3 transferase. We monitored the monolayer barrier integrity by transendothelial electrical resistance assay (TEER),activity of RhoA by pull down assay,NF-κB by luciferase reporter assay,and F-actin dynamic structure by Rhodamine-phalloidin staining. Results Incubation of monolayers with LPS caused substantial barrier hyperpermeability. Under the had been treated for 3 and 12 h with LPS (P<0.05). Such effects could be inhibited partly by pretreatment of RhoA inhibitor exoenzyme C3 transferase. LPS activated RhoA and NF-κB at 0.5 h. The C3 transferase could significantly reverse the NF-κB activation (P<0.05). The F-actin rearrangments displayed in a time-dependent manner and occurred originally after the stimulation of LPS for 3 h,which could be diluted by the pretreatment of C3 transferase as well. Conclusion LPS induces the disruption of F-actin cytoskeleton and brain microvascular endothelial barrier integrity,in part,through RhoA and NF-κB activation. The mechanism underlying this pathophysiological effect of RhoA is to influence the disruption of the F-actin cytoskeleton by regulating NF-κB activites.

Objective To study the gene expression profiles of megakaryocytes(MKs) from human cord blood CD34+ cells in vitro expanded and to understand megakaryopoiesis at the molecular level. Methods CD34+ cells were isolated using density gradient centrifugation and magnetic activated cell sorting. The cells were cultured and stimulated with recombinant human TPO ( 100 ng/ml). After 12 days, the MKs fraction was separated using an anti-CD41 monoclonal antibody by immunomagnetic sorting. The gene expression profiles of MKs, non-MKs as well as meg-01 cells were studied by gene chip assay. THBSI, HOX A9,β-actin, lL-8,Annexin A6, FGF-8 were selected to validate the gene chip results by RT-PCR. Results A total of 116 genes between MKs and non-MKs cells were significantly different, 52 genes were up-regulated and 64 genes were down-regulated. In addition, 158 genes between MKs and meg-01 cells were significantly different, 71 genes were up-regulated and 87 genes were down-regulated. THBSI showed higher expression in MKs than in non-MKs. HOXA9 showed lower expression in MKs than in non-MKs. The expression of β-actin did not show any significant difference in MKs and non-MKs. IL-8 showed higher expression in MKs than in meg-01 cells, while ANXA6 showed lower expression in MKs than in meg-01 cells. The expression of FGF-8 did not show any significant difference between MKs and meg-01 cells. Conclusions MKs, non-MKs and meg-01 cells show different gene expression profiles. The regulatory genes include stress response genes,immune related genes, DNA synthesis and repair genes, metabolism genes, pro-onco genes and tumor suppressor genes.

OBJECTIVEGram-negative bacteria-induced multiple organ failure/dysfunction syndrome (MOF/MODS) is one of the leading causes of death through the world. The member of immunoglobulin family programmed death-1 (PD-1) is a negative immune regulator. This study investigated the protective effect of PD-1 as well as the underlying mechanism in LPS-induced endotoxemia.
METHODSTen PD-1(+/+) and ten PD-1 knockout (PD-1(-/-)) mice were injected peritoneally with LPS (10 mg/kg), and the survival was observed within 72 hrs after LPS injection. The other 40 PD-1(+/+) and 40 PD-1(-/-) mice were injected peritoneally with LPS (5 mg/kg). Blood samples were collected before injection and 1.5, 3 and 6 hrs after LPS injection (n=10 each time point). Serum levels of various inflammatory mediators were measured using ELISA.
RESULTSThe survival rate in PD-1(-/-) mice was noticeably lower than that in PD-1(+/+) mice after 10 mg/kg LPS injection. Serum levels of inflammatory mediators TNF-α, IL-1β, IL-12 and IL-17 in PD-1/mice were higher than those in PD-1(+/+) mice after 5 mg/kg LPS injection.
CONCLUSIONSPD-1 can protect mice from LPS-induced endotoxemia probably through its regulation on inflammatory mediator production.
