Phagocytosis of optically-trapped particles: delivery of the pure phagocytic signal

cell Research 2006年第11期16卷 8+853-854页

作者： Maurjce B hallett UK Neutrophil Signalling Group School of Medicine cF14 4XN cardiff University

Phagocytosis is a fundamental cell biological process exhibited by a wide variety of cell types from single cell organ-isms,which rely on this for feeding,to phagocytes in higher animals,which rely on specialised immune cells for com-bating infecting *** the immune system,both macrophages and neutrophils play roles as *** are often called"professional phagocytes"because of their remarkable capacity for phagocytosis,beingable to internalise microscopic particles(diam 0.5-3 μm)of virtually any surface *** efficiency and speedof phagocytosis is,however,increased by coating the surface of the particles with opsonins such as antibodies or thecomplement component c3bi(acting on β2 integrin receptors),and c3bi-accelerated phagocytosis by neutrophils is thefirst line of defence by the innate immune system in vivo,operating in advance of the slower production of *** the mechanism of phagocytosis is,therefore,clearly an important goal.

肌张力障碍患者基底节及丘脑神经元活性

世界核心医学期刊文摘（神经病学分册） 2005年第2期1卷 21-22页

作者： hallett M. 陈云春

Objective: To explore the role of abnormal neuronal activity in the basal gang lia and thalamus in the generation of dystonia. Methods: Microelectrode recordin g was performed in the globus pallidus internus (GPi), ventral thalamic nuclear group ventral oral posterior/ventral intermediate, Vop/Vim) and subthalamic nucl eus (STN) in patients with primary dystonia (n=11) or secondary dystonia (n=9) d uring surgery. Electromyogram (EMG) was simultaneously recorded in selected musc le groups. Single unit analysis and cross correlations were carried out. Result s: Three hundred and sixty seven neurons were obtained from 29 trajectories (GP i: 13; Vop/Vim:12; STN: 4), 87%exhibited altered neuronal activity including gr ouped discharges in GPi (n=79) and STN (n=37), long lasting neuronal activity ( n=70) and rapid neuronal discharge (n=86) in Vop/Vim. There were neurons in Vop, GPi and STN firing at the same frequency as EMG during dystonia (mean: 0.39 Hz, range 0.12-0.84 Hz). Significant correlations between neuronal activity and EM G at the frequency of dystonia were obtained (GPi: r2=0.7 (n=31), Vop/Vim: r2=0. 64 (n=18) and STN: r2=0.86 (n=17)). conclusions: consistent with previous findin gs of abnormalities observed in Vop/VIM and GPi in relation to dystonia, the pre sent data further show that the altered activity in GPi, specifically in dorsal subregions of GPi, Vop/Vim and STN is likely to be directly involved in the prod uction of dystonic movement. Dystonia related neuronal activity observed in mot or thalamus and basal ganglia nuclei of GPi and STN indicates a critical role of their interactions affecting both indirect and direct pathways in the developme nt of either generalized or focal dystonia. Significance: These data support a c entral role of the basal ganglia in producing dystonic movements.
