PROBLEM To investigate possible roles of the natural killer (NK) cell receptor killer immunoglobulin-like receptor (KIR)2DL4 expressed on uterine NK (uNK) cells during pregnancy, we investigated KIR2DL4 expression on uNK cells isolated from patients with early recurrent spontaneous abortion (RSA) and normal early pregnancy women, and functions of KIR2DL4(More)
Human leukocyte antigen(HLA)-G could inhibit functions of immune cells and induce regulatory T cells (Treg) and could be involved in antitumor immune responses. In the current study, HLA-G expression in 58 primary breast cancer lesions was analyzed with immunohistochemistry. Plasma soluble HLA-G was detected with enzyme-linked immunosorbent assay in 92(More)
To investigate the changes of platelet activated state and platelet activated function by trace whole blood flow cytometry (FCM), and to explore the mechanism of hemorrhage and infiltration in adults with acute leukemia, the expression percentage and changes of these expressions of CD62p and PAC-1 on platelet surface were determined by FCM of trace whole(More)
BACKGROUND Alteration of HLA expression or cytokine production plays a crucial role in the pathogenesis of human cytomegalovirus (HCMV) infection. HLA-G has been suggested to be involved in HCMV infection, and modulation of HLA-G expression by interferon (IFN)-gamma and interleukin (IL)-10 has been reported. However, the clinical relevance of HLA-G in HCMV(More)
Amniotic fluid cells (AFCs) are routinely obtained and expanded in vitro for prenatal diagnosis; nevertheless current knowledge about their properties is limited. The detailed mechanisms underlying normal pregnancies are yet to be discovered. The goal of this study was to identify the immunological aspects of AFCs including cytokine production and human(More)
A novel H1N1 virus of swine origin (H1N1v) recently caused a pandemic; however, knowledge of immunologic aspects of the virus infection are limited. Human leukocyte antigen-G (HLA-G) was speculated to play critical roles in viral infection, although its clinical relevance in H1N1 infection remains unknown. In this study, HLA-G expression in peripheral T(More)
The suppressive functions of HLA-G to various immune cells have been well established. The proportion of HLA-G expression in malignant lesion cells was found from negative to 100%. However, effects for the different proportion of HLA-G expression on the cytolysis of NK cells remain to be explored. In this study, NK cytolysis to the various proportion of(More)
OBJECTIVE To investigate the effects of anti-CD44 mAb A3D8 on the cell proliferation of human acute monocytic leukemia cell line THP-1 and its mechanism. METHODS Cell proliferation was assayed with MTT method, the expression of CD33, CD15, CD11b, CD14, Annexin-V, caspase-3 and cell cycle with flow cytometry, and the expression of p-Akt, p-ERK, bcl-2 and(More)
The cerebellar deficit hypothesis for developmental dyslexia claims that cerebellar dysfunction causes the failures in the acquisition of visuomotor skills and automatic reading and writing skills. In people with dyslexia in the alphabetic languages, the abnormal activation and structure of the right or bilateral cerebellar lobes have been identified. Using(More)
The present study examined the effects of orthographic neighborhood (N) size on the cognitive processes underlying Chinese character reading. Previous research has shown increasing N size facilitates word naming and recognition performance in alphabetic languages. Experiment 1 revealed that a large N size was associated with a general inhibition of(More)
