... Abstract Background: In the traditional theory of albuminuria, small amounts of albumin pass through the fenestrae in glomerular endothelial cells, then through the slit membrane in the gaps between foot processes of glomerular epithelial cells. In the novel theory, large amounts of albumin...

... Epithelial proliferative lesions of the breast are a heterogeneous group of intraepithelial lesions that includes ductal hyperplasia without atypia, atypical ductal hyperplasia (ADH), low-grade ductal carcinoma in situ (DCIS), glandular adenosis, intraductal papillomas, lobular intraepithelial...

..., to establish acquired immunity. NALT consists of epithelial cells, epithelium-associated lymphoid tissues such as IgA-committed B cells, innate lymphocytes, T helper cells and dendritic cells. Intranasal immunization has recently been shown to effectively induce a proactive immune response in the local mucosa...

... is required. Recent studies have revealed that epithelial cell-derived cytokines, including thymic stromal lymphopoietin, interleukin (IL)-25 and IL-33, are able to control immune cells, such as dendritic cells and T cells, thereby acting as ‘master switches' in allergic disease. In addition, new roles have...

... Abstract The majority of retinal pigment epithelial (RPE) tumors are considered to be congenital and benign. They are classified as either congenital hypertrophy of the RPE (CHRPE) or RPE hamartoma. CHRPE most frequently presents as an isolated, flat, darkly pigmented and well-delineated fundus...

... observed in IBD. Although it has not been completely elucidated how TNF-α damages intestinal epithelial cells (IECs), recent reports have shown various effects of TNF-α on IECs that may be involved in the pathogenesis of IBD. In this section, we review the various functions of TNF-α in IECs...

...Highlights 1. Lung carcinomas are the most frequent cause of a positive EBUS-TBNA, with non-small-cell lung carcinoma (NSCLC) being the most common (70%). Other subtypes of primary lung epithelial neoplasms seen in EBUS-TBNA include small-cell carcinoma, atypical carcinoid, large-cell...

... is associated with the infiltration to the tubulointerstitium by inflammatory cells. Previous findings suggest that soluble mediators from renal tubular epithelial cells (TEC) stimulate the proliferation of mesangial cells, which involves a bi-directional tubuloglomerular ‘crosstalk' mechanism, and is likely...

.... The epithelial barrier function is regulated in large part by the apical-most intercellular junction, referred to as the tight junction. Antigen-presenting cells, particularly dendritic cells (DCs), are known to play an important role in human nasal mucosa. Recently, the author and colleagues discovered a new...

... Abstract Respiratory syncytial virus (RSV) primarily infects upper respiratory tract cells, mainly nasal epithelial cells. The tight junctions of nasal epithelial cells are thought to perform important innate immune function against foreign materials including respiratory viruses. We...

... Abstract Parietal epithelial cells of Bowman’s capsules were first described by Sir William Bowman in 1842 in his paper On the Structure and Use of the Malpighian Bodies of the Kidney [London, Taylor, 1842], but since then their functions have remained poorly understood. A large body...

... epithelial cells expanded on amniotic membrane (AM). Methods: Forty-four eyes of 38 patients (27 male, 11 female) with total (n = 32) or partial (n = 12) LSCD were treated by transplantation of autologous (n = 30) or allogeneic (n = 14) limbal epithelial cells expanded on intact AM. LSCD was caused...

... Abstract Salivary gland organogenesis involves the specification, maintenance, lineage commitment, and differentiation of epithelial stem/progenitor cells. Identifying how stem/progenitor cells are directed along a series of cell fate decisions to form a functional salivary gland...

... epithelial cells systems (TEC) were developed to study early host responses to AIV infection on TEC. Infection of 2 week-old chickens and ducks with the highly pathogenic AIV H5N1 Ck/Hong Kong/220/97 and Egret/Hong Kong/757.2/02 viruses together with TEC early responses to infection suggest the induction...

... Abstract Background/Aims: It is still controversial that hyperplastic epithelial lesions of the pancreaticduct are always pre-neoplastic conditions. This is an attempt to reclassify ‘hyperplasticlesions’ apart from low-grade neoplastic lesions, such as intraductal papillary-mucinous adenomaor...
