Dendritic cells are present in both lymphoid and non-lymphoid organs, which heterogenous group of nonphagocytic nonlymphoid immune accessory cells. Plasmacytoid dendritic cell (which has an eccentric nuclei) subset aid secreting high levels type 1 interferons by activation gaining like morphology, play important role antiviral immunity involved initiation development stages inflammatory respons...

non hodgkin lymphomas (nhl) are nodal or extra nodal monoclonal infiltrations by malignant lymphoid cells (b lymphocytes in 80% of cases), which are distinguished as indolent or aggressive forms. according to the heterogeneity of lymphoid cells and their ubiquitous anatomical distribution, these disorders can develop in any organ and have very heterogeneous clinical expressions, but they are us...

Introduction. The development of rabbit farming requires the breeding new breeds rabbits with accelerated growth intensity and increased productivity. Together acceleration somatic systems, rates morphogenesis formation organs that provide immune protection, in particular, lymphoid formations intestine, also change [1, 2]. Lymphoid associated intestinal mucosa mammals are represented by diffuse...

the histopathologic diagnosis of orbital and ocular adnexal lymphoproliferative lesions is difficult, resulting controversy in classification, determining benignity or malignancy of them and treatment modality selection. we designed the following study to evaluate clinical, histopathologic and if necessary immunochemical features of them in decreasing indeterminate cases. the study includes 51 ...

It is unclear why aging causes a drop in lymphoid-biased HSC numbers and decline lymphoid progenitor quality. One possibility that stem cells have inherently programmed processes at work, which would imply these an internal clock controls their functionality lifetime. This study aims to summarize current evidence regarding the Effect of on White Blood Cells Count immunity. The PubMed database E...

Introduction Dendritic cells (DCs) are bone marrow-derived cells, which migrate to lymphoid and non-lymphoid organs via blood. Liver DCs are believed to play an important role in the regulation of hepatic allograft acceptance. However, because of inherent difficulties in isolating adequate numbers of DCs from liver, limited information is available on the phenotype and functions of liver DCs. ...

purpose: to report five cases of benign reactive lymphoid hyperplasia of the caruncle and plica and describe their clinical course and pathology. case report: five patients with fish flesh pinkish masses in the caruncle and plica were referred to labbafinejad hospital from 1997 to 2006. the masses were excised. clinical appearance and course as well as pathology and immunohistochemistry confirm...

Pulmonary nodular lymphoid hyperplasia (PNLH) is a reactive lymphoid proliferation manifesting as multiple solitary nodules or localized infiltrates in the lungs. It is a type of benign lymphoproliferative disease that can affect the lungs. We present the case of a 41-year-old female patient with respiratory symptoms such as productive cough, left chest pain, and dyspnea. Imaging findings revea...
