Gut bacteria side-step lymph nodes
To migrate out of blood vessels into inflamed tissues, blood cells must cross both the vessel endothelium and basement membrane (BM). According to Wang and colleagues (page 1519), protein-sparse exit sites in the BM pave the way for this cellular escape. The signals required for blood cells to adhere to sites of vessel inflammation and to squeeze through endothelial cell (EC) junctions are well...
متن کاملSonography of neck lymph nodes. Part I: normal lymph nodes.
Grey scale and power Doppler sonography play an important role in assessment of cervical lymphadenopathy. However, before examination of pathological nodes, a clear understanding of the anatomy of cervical nodes, scanning technique and sonographic appearances of normal cervical nodes is essential. This article reviews these topics in order to provide a baseline for sonographic examination of ce...
متن کاملMesenteric lymph nodes infection with Linguatula serrata nymphs in cattle
871 mesenteric lymph nodes taken from 110 native cattle from Urmia slaughter-house with differentages were examined for Linguatula serrata infection. The lymph nodes were studied based on their colourand consistency. 44% of the cattle were found positive for L. serrata infection. The number of parasitesisolated from each infected lymph node varied from 1 to 69 with a mean of 5.48. There were no...
متن کاملCD8+ T Lymphocyte Subsets in Bladder Tumor Draining Lymph Nodes
Background: Cytotoxic CD8+ T cells, as essential parts of the adaptive immune system, play pivotal roles in anti-tumor immune responses. It is well documented that cytokine expression profiles and activation status of these cells during anti-tumor immune responses affect the outcome of host-tumor interaction. Objective: To investigate the percentages of CD8+ lymphocytes and their subsets in...
متن کاملWhy lymph nodes grow
At the initiation of an immune response, lymph nodes can double in size in a day and can be ten times their original size in five to seven days. Webster and colleagues report on page 1903 that dendritic cells, quite distinct from their function in antigen presentation, stimulate endothelial cell proliferation and vascular growth in the growing lymph node. Peripheral challenge (such as immunizat...
