to study the immunohistochemical pattern of cd 117, glial fibrillary acidic protein (gfap), smooth muscle actin (sma) and cd 43 in pleomorphic adenoma (pa), adenoid cystic carcinoma (adcc) and polymorphous low grade adenocarcinoma (plga) of minor salivary glands.twenty cases of pa, 20 cases of adcc and 10 cases of plga were retrieved from record files along with their paraffin blocks at armed f...
Introduction: There are few studies investigating the role of neoangiogenesis in biological behavior of salivary gland tumors. CD105 expression has demonstrated greater accuracy for detecting new vessel formation compared with other pan-endothelial molecules. This study aimed to assess and compare intratumoral Micro-Vessel Density (MVD) through using immunohistochemichal expression of CD105 bio...
Antibody-dependent cellular cytotoxicity (ADCC) may assist in preventing HIV or delaying disease progression. Most prior studies have analysed Env-specific ADCC responses. We hypothesized that effective ADCC-based immunity may target conserved internal viral proteins such as Pol. We analysed the ability overlapping Pol peptides to induce activation of NK cells via ADCC. We prospectively studied...
adenoid cystic carcinoma (adcc) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). about 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). three clinically obvious characteristics of adcc include slow growth rate, perineural invasion and high incidence of distant metastasis (1). the most commonly-affected sites of...
OBJECTIVE Increasing data support a role for antibody-dependent cellular cytotoxicity (ADCC) in controlling HIV-1 infection. We recently isolated a naturally occurring dimeric form of the anti-HIV-1 antibody 2G12 and found it to be significantly more potent than 2G12 monomer in neutralizing primary virus strains. However, given the unusual structure of dimeric 2G12 with two Fc regions, it was n...
مقدمه: موکواپیدرموئید کارسینوما ((mec و آدنویید سیستیک کارسینوما (adcc) شایع ترین تومورهای بدخیم غدد بزاقی هستند که رفتار بیولوژیک آنها کاملا مشخص نشده است. از عواملی که در رفتار بیولوژیک این تومورها موثر قلمداد شده است، تهاجم اطراف عصبی و عروقی میباشد. لذا هدف این مطالعه، بررسی تهاجم اطراف عصبی و عروقی adcc و mec غدد بزاقی اصلی و فرعی با استفاده از مارکرهای ncam، s-100، gfap به عنوان مارکرهای...
OBJECTIVE The objective of this study is to determine the breadth of HIV-1 Env-specific antibody-dependent cellular cytotoxicity (ADCC) in HIV controllers and HIV progressors with a view to design globally relevant HIV vaccines. DESIGN The breadth of ADCC towards four major HIV-1 Env subtypes was measured in vitro for 11 HIV controllers and 11 HIV progressors. METHODS Plasma from 11 HIV con...
The antibody-dependent cell-mediated cytoxicity (ADCC) by human monocytes and neutrophils was investigated by measuring the release of 51chromate from prelabeled erythrocytes coated with immunoglobulin G. ADCC was found to be positively correlated to phagocytosis of 51Cr-labeled erythrocytes and to the postphagocytic events of the effector cells, activation of the hexose monophosphate shunt, an...
SummaryIn humans, pre-existing anti-HIV-1 neutralizing antibodies (nAbs) have not been associated with decreased HIV-1 acquisition. We evaluated antibody-dependent cellular cytotoxicity (ADCC) present in pre-transmission infant and maternal plasma breast milk (BM) against the contemporaneous variants. exposed uninfected as compared to infected infants had higher ADCC a combination of nAb respon...
UNLABELLED Elucidating the factors that modulate HIV-specific antibody-dependent cellular cytotoxicity (ADCC) will help in understanding its role in HIV immunity. The aim of this study was to determine whether IgA could modify the magnitude of ADCC in HIV infection, abrogating its protective role. Plasma samples from 20 HIV-positive (HIV(+)) subjects enrolled during primary HIV infection (PHI),...
