Introduction: Previous research on autoimmune skin blistering diseases (ABD) has primarily focused on the humoral immune response; moreover, little attention has been given to the potential role of the antigen presenting cells (APCs) in lesional skin. Aim: The purpose of our study was to immunophenotype selected APC in the lesional skin of ABDs, utilizing immunohistochemistry (IHC) stains. Mate...
Tumor-associated macrophages (TAMs) can elicit contrasting effects on tumor progression, depending on different tumor microenvironment. This study aimed to explore the correlation between TAM infiltration and clinicopathologic characteristics, metastasis, and prognosis of supraglottic laryngeal carcinoma. TAMs in intratumoral and peritumoral regions of 84 specimens of supraglottic laryngeal car...
HLA-DR overexpression in tubules of renal allografts during early and late renal allograft injuries.
OBJECTIVES We sought to discover which types of injuries were related to human leukocyte antigen DR expression in acute rejection and late chronic injury in renal allografts. MATERIALS AND METHODS Ninety-two recipients were separated into the early acute rejection group, the late monocyte infiltration group, and the late chronic injury group. Ten subjects with acute cellular rejection receive...
Dendritic cells (DCs) are potent antigen-presenting cells (APCs). Among so-called professional APCs, only DCs can activate naive T cells to initiate immune response. To better understand molecular mechanisms underlying unique functions of DCs, we searched for genes specifically expressed in human DCs, using PCR-based cDNA subtraction in conjunction with differential screening. cDNAs generated f...
AIMS AND BACKGROUND Epithelioid angiosarcoma is a rare histopathologic variant of angiosarcoma characterized by an epithelioid morphology. This subset can histologically mimic non-vascular neoplasms and impose serious challenges in reaching a correct diagnosis, especially in the context of limited tissue sampling (e.g., needle core biopsy). To improve recognition of epithelioid angiosarcoma - a...
A 4-month-old infant presented with asymptomatic soft nodules on his right forearm, which had developed since birth. On the suspicion of nevus lipomatosus superficialis (NLS), biopsy was performed. Histopathologic findings showed monomorphic polygonal cells with abundant granular cytoplasm. Immunohistochemical stains for CD68 and vimentin were strongly positive, but were negative for S-100 prot...
BACKGROUND Axillary hyperpigmentation is a frequent cause of cosmetic consultations in dark-skinned women from tropical areas, including Latin America. Currently, there is no widely accepted treatment for the disorder, but it is usually treated with bleaching agents because it is considered a variant of inflammatory hyperpigmentation. The purpose of this study was to assess the efficacy of niac...
Human Adipose Tissue Macrophages Are Enhanced but Changed to an Anti-Inflammatory Profile in Obesity
OBJECTIVE Adipose tissue (AT) macrophages are increased in obesity and associated with low grade inflammation. We aimed to characterize the phenotype of AT macrophages in humans in relation to obesity and insulin resistance. DESIGN Gene-expression levels of general macrophage markers (CD68 and CD14), proinflammatory markers/M1 (TNF-α, MCP-1, and IL-6), and anti-inflammatory markers/M2 (CD163,...
It is not clear if 18FDG-PET can be useful for detection of inflammation in low to moderate carotid stenosis. We studied 15 patients scheduled for endarterectomy with contralateral carotids with less than 50% stenosis. 18-FDG-PET was performed prior to CEA and 3 months following surgery. FDG-uptake values were calculated based on maximum standardized uptake value (SUV) and corresponding uptake ...
