We report a biomimetic delivery of microsized capsule-cushioned leukocyte membrane vesicles (CLMVs) through the conversion of freshly reassembled leukocyte membrane vesicles (LMVs), including membrane lipids and membrane-bound proteins onto the surface of layer-by-layer assembled polymeric multilayer microcapsules. The leukocyte membrane coating was verified by using electron microscopy, a quar...

kcnk2 was previously shown to regulate immune-cell trafficking into the central nervous system (cns). kcnk2-/- mice demonstrated a more severe disease course in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, due to an increased immune-cell migration into the cns. an upregulation of the cellular adhesion molecules icam1 and vcam1 on brain endothelial cells in k...

RNA interference (RNAi) has advanced into clinical trials. In spite of the progress made in systemic RNAi delivery to the liver and solid tumors, delivery of RNAi to leukocytes remains challenging and less advanced. Manipulating leukocyte function with RNAi holds great promise for streamlining the drug discovery process by facilitating in vivo drug target validation and for facilitating the dev...

BACKGROUND Lenalidomide is a thalidomide analogue that may serve as an adjunctive therapy for treatment-refractory cutaneous lupus erythematosus (CLE). OBJECTIVES We evaluate the use of lenalidomide in CLE and describe the skin and circulating leukocyte profile of treatment-refractory patients before and after treatment. METHODS Five subjects were treated with lenalidomide in an unblinded o...

OBJECTIVE: To evaluate the necessity of weekly monitoring by means of leukocyte and platelet counts of patients with head and neck, chest, and pelvis cancer submitted to conventional radiotherapy. MATERIALS AND METHODS: A hundred and one adult patients with cancer of head and neck (n = 11), chest (n = 35) and pelvis (n = 55), submitted to radiotherapy were assessed by means of leukocyte and pla...

oxidative stress mediated by reactive oxygen species is known to contribute to the inflammatory process of bronchial asthma. reactive oxygen species are released into the bronchial tree by activated inflammatory cells. in this study, we aimed to determine the effect of vitamin c administration on leukocyte vitamin c level as well as severity of asthma. in this double blind clinical trial study ...

Increased susceptibility to atherosclerosis increases the risk of mortality in type 2 diabetic patients. Leukocyte adhesion to the endothelium is a critical step in atherogenesis. In addition to its insulin-sensitizing effects, rosiglitazone (RSG) possesses anti-inflammatory properties. However, the effects of RSG on the initial phase of leukocyte recruitment (rolling, adhesion) have not been s...

The mechanism of IFN-β therapy in relapsing-remitting multiple sclerosis (RRMS) is not well understood, but induction of apoptosis in specific leukocyte subsets is likely to be important. Enhanced expression of TNFSF10 or TNF-related apoptosis-inducing ligand (TRAIL) mRNA in unseparated leukocytes has been put forward as a therapeutic response marker, but it is unclear which leukocyte subsets e...

OBJECTIVE In this preliminary presentation the outcome of women following systemic treatment of cervical human papilloma virus (HPV) with a leukocyte ultrafiltrate is reported. METHODS Cervical brush specimens of 819 women with low-grade CIN-1 were evaluated for HPV infection. HPV-positive patients were treated either by cone biopsy because of suspicious colposcopy or by antibiotics for sympt...

Leukocyte-endothelial cell interactions and leukocyte activation are important factors for vascular diseases including nephropathy, retinopathy and angiopathy. In addition, endothelial cell dysfunction is reported in vascular disease condition. Endothelial dysfunction is characterized by increased superoxide (O(2) (•-)) production from endothelium and reduction in NO bioavailability. Experiment...
