PROBLEM: To determine if altered trophoblast CD200 and CD200R expressions promote inflammatory cytokine production in preeclamptic placentas. METHODS OF STUDY: Placental tissue CD200 and CD200R expressions were determined by immunostaining. Tissue sections from first-, second-, and third-trimester, normal term, and preeclamptic placentas were used. CD200 and CD200R expressions and cytokine production of TNFα, sTNFR1, INFγ, IL-4, IL-6, IL-8, and IL-10 were determined in trophoblasts from normal and preeclamptic placentas and in normal trophoblasts transfected with CD200 siRNA...

Osteocytes are master orchestrators of bone remodeling; they control osteoblast and osteoclast activities both directly via cell-to-cell communication and indirectly via secreted factors, and they are the main postnatal source of sclerostin and RANKL (receptor activator of NF-kB ligand), two regulators of osteoblast and osteoclast function. Despite progress in understanding osteocyte biology and function, much remains to be elucidated. Recently developed osteocytic cell lines-together with new genome editing tools-has allowed a closer look at the biology and molecular makeup of these cells...

BACKGROUND: Multiple myeloma (MM) is an incurable disease characterized by clonal plasma cell (PC) proliferation within the bone marrow (BM). Next-generation flow cytometry has become the reference tool to follow minimal residual disease (MRD). We developed a new simpler and cheaper flow cytometry method to analyze bone marrow samples in patients with MM. METHODS: To identify and characterize abnormal PC, we designed a simple panel composed of anti-CD38, anti-kappa and anti-lambda light chain antibodies, combined with two antibody pools with the same fluorophore (anti-CD19 and anti-CD27 for the negative pool, and anti-CD56, anti-CD117 and anti-CD200 antibodies for the positive pool)...

The modified Matutes score has been the basis for the diagnosis of chronic lymphocytic leukaemia (CLL) by flow cytometry for the past 15 years. To increase the specificity of the current score we systematically evaluated the diagnostic value of established as well as novel markers, such as CD200, in a large cohort of patients with untreated B-cell malignancies (n = 370). Double positivity for CD5 and CD23 was of very high value to differentiate between CLL and non-CLL cases. In addition, lack of FMC7 expression as well as CD79b expression intensity showed high sensitivity (90·4% and 92·3%) with acceptable specificity (74·4% and 76·9%)...

Various strategies have been utilized to improve both gene transfer efficiency and cell-induced toxicity of polyethylenimine (PEI), the most extensively investigated cationic polymeric vector. In this study, we sought to enhance transfection efficiency of low molecular weight PEI (LMW PEI) while maintaining its low toxicity by cross-linking LMW PEI via succinic acid linker. These modifications were designed to improve the hydrophilic-hydrophobic balance of the polymer, by enhancing the buffering capacity and maintaining low cytotoxic effects of the final conjugate...

CD200 has been reported to be neuroprotective in neurodegenerative diseases. However, the potential protective effects of CD200 in germinal matrix hemorrhage (GMH) have not been investigated. We examined the anti-inflammatory mechanisms of CD200 after GMH. A total of 167 seven-day-old rat pups were used. The time-dependent effect of GMH on the levels of CD200 and CD200 Receptor 1 (CD200R1) was evaluated by western blot. CD200R1 was localized by immunohistochemistry. The short-term (24 h) and long-term (28 days) outcomes were evaluated after CD200 fusion protein (CD200Fc) treatment by neurobehavioral assessment...

The incidence of B-cell chronic lymphoproliferative disorders (B-CLPDs) is significantly lower in China than that in western countries. There have been studies involving small cohorts with conflicting results regarding the spectrum of B-CLPDs in China, and the types and immunophenotyping of B-CLPDs in China remain largely unexplored. We conducted a retrospective analysis of 653 cases of B-CLPDs seen in our centre from 2011 to 2015. Four-colour flow cytometry was used to determine the expression of each immunological marker, and the diagnostic values of the immunological markers were also investigated...

Biocompatibility is a major concern for developing biomaterials used in medical devices, tissue engineering and drug delivery. Poly(lactic-co-glycolic acid) (PLGA) is one of the most widely used biodegradable materials, yet still triggers a significant foreign body response that impairs healing. Immune cells including macrophages respond to the implanted biomaterial and mediate the host response, which can eventually lead to device failure. Previously in our laboratory, we found that CD200, an immunomodulatory protein, suppressed macrophage inflammatory activation in vitro and reduced local immune cell infiltration around a biomaterial implant...

BACKGROUND: Hair follicles are known to contain a well-characterized niche for adult stem cells: the bulge, which contains epithelial and melanocytic stem cells. Stem cells in the hair bulge, a clearly demarcated structure within the lower permanent portion of hair follicles, can generate the interfollicular epidermis, hair follicle structures, and sebaceous glands. The bulge epithelial stem cells can also reconstitute in an artificial in vivo system to a new hair follicle. METHODS: In this study, we have developed a new method to isolate human adult stem cells by mechanical centrifugation of punch biopsy from human hair follicles without culture condition...

BACKGROUND: Ibrutinib has been shown to have immunomodulatory effects by inhibiting Bruton's tyrosine kinase (BTK) and IL-2-inducible T cell kinase (ITK). The relative importance of inhibiting these 2 kinases has not been examined despite its relevance to immune-based therapies. METHODS: Peripheral blood mononuclear cells from chronic lymphocytic leukemia (CLL) patients on clinical trials of ibrutinib (BTK/ITK inhibitor; n = 19) or acalabrutinib (selective BTK inhibitor; n = 13) were collected serially...

OBJECTIVE: Atypical CLL is most frequently confused with mantle cell lymphoma (MCL). Several markers may contribute to the diagnosis of CLL. However, there is no consensus on which markers are needed to be used in the flowcytometry for the diagnosis of CLL. The aim of the present study was to investigate the role of CD43 and CD200 markers in the differential diagnosis between CLL and MCL. MATERIALS AND METHODS: To address this issue, 339 consecutive patients with CLL and MCL evaluation of CD43, and CD200 expressions were included in the flowcytometry LPD panel but not in the Matutes scoring system...

Neuroinflammation is an important pathogenesis of Parkinson's disease (PD). The peripheral immune system could produce profound effects on central immunities. The peripheral blood monocyte (PBM) immune tolerance is the refractoriness of immune system to avoid overactive peripheral inflammation. The PBM are also actively involved in central immune activities. There is evidence implying the probable failure of immune tolerance and impairment of CD200/CD200R signaling in PD patients. Here we aimed to explore the effects of PBM tolerance in peripheral LPS-induced neuroinflammation as well as the specific roles of CD200/CD200R pathway in PBM tolerance...

OBJECTIVE: Overexpression of ABCG2 and CD200 has been independently associated with poor outcome in acute myeloid leukemia (AML). However, no data are available on the role of these two factors in patients with core-binding factor (CBF)-positive or FLT3-negative/NPM1-mutated cytogenetically normal (CN) AML. METHODS: We analyzed 65 adult AML patients with CBF+ (n=16) or FLT3-/NPM1+ CN (n=49), evaluating clinical and biological factors associated with complete remission attainment, leukemia-free survival (LFS) and overall survival (OS)...

Interleukin-15 receptor alpha (IL15RA) is an important component of interleukin-15 (IL15) pro-inflammatory signaling. In addition, IL15 and IL15RA are present in the circulation and are detected in a variety of tissues where they influence physiological functions such as muscle contractility and overall metabolism. In the skeletal system, IL15RA was previously shown to be important for osteoclastogenesis. Little is known, however, about its role in osteoblast function and bone mineralization. In this study, we evaluated bone structural and mechanical properties of an Il15ra whole-body knockout mouse (Il15ra(-/-)) and used in vitro and bioinformatic analyses to understand the role IL15/IL15RA signaling on osteoblast function...

The CD200/CD200R signalling pathway downregulates the synthesis of proinflammatory mediators and induces the synthesis of antiinflammatory mediators in macrophages and microglia. However, very little is known about the effect of this immunosuppressive pathway on the synthesis of lipid mediators. Therefore, we determined the synthesis of 35 lipids spanning 5 different lipid families in bone marrow-derived macrophages, which were treated with interleukin (IL) 4, IL10, lipopolysaccharide (LPS), or interferon γ (IFNγ) in absence and presence of CD200...
