  anterograde transport
COPI-coated vesicles are involved in retrograde-directed selective transport of proteins from the Golgi complex to the endoplasmic reticulum (ER) as well as mediate anterograde transport of cargo proteins within the Golgi or in endosomal trafficking.
      
Furthermore, the effects of aluminium on anterograde transport mechanisms were reversible 8 days after removal of aluminium.
      
Hence, functional alterations of the anterograde transport caused by aluminium could be detected even after short exposure periods.
      
This analysis revealed an impaired anterograde transport of HRP already after a short aluminium intoxication period of only 1 hour in DRG cells in vitro, an effect that increased with a prolonged aluminium exposure for up to 10 days.
      
This pattern suggests that the 'clearing' of axonally transported materials from the distal stump by continued anterograde transport may underlie axonal breakdown after transection.

It has been found by Ju('81)that HRP could be anterogradely transported forlong distances.Based on this fact the rate of anterograde transport was investigatedin the present study,and,at the same time,the rate of retrograde transport and thetime of disappearance of HRP from the labeled sites were observed.Twenty tworabbits,weighing 2~2.2 kg,were used.The HRP was injected into the lower lumbarspinal cord unilaterally.The animals were sacrificed after 12 hours to 7 days andwere processed with benzidine...

It has been found by Ju('81)that HRP could be anterogradely transported forlong distances.Based on this fact the rate of anterograde transport was investigatedin the present study,and,at the same time,the rate of retrograde transport and thetime of disappearance of HRP from the labeled sites were observed.Twenty tworabbits,weighing 2~2.2 kg,were used.The HRP was injected into the lower lumbarspinal cord unilaterally.The animals were sacrificed after 12 hours to 7 days andwere processed with benzidine and o-dianisidine.The anterogade labeling in the dorsalaccessory olivary nucleus and the retrograde labeling in the red nucleus and thenucleus raphe pallidus were chosen for study.It was quite unexpected to find that the anterograde and retrograde labelingsparalled each other in time as well as in intensity.They appeared at the same timeand waxed and waned practically in full accord.Labeling of the brainstem firstappeared at 18 hour's survival,reached its peak at the 2nd day,and then graduallyfaded away till at the 7th day when only traces of labeling remained.In the casewhich showed the earliest labeling the distance between the injection site and theobex,which was at about the same level as the most densely labeled parts of thedorsal accessory olivary nucleus and nucleus raphe pallidus,was measured to be 265mm and the rate of transport,the same for anterograde and retrograde transports,was calculated to be more than 350mm per day.Counting from the time of theearliest labeling,HRP was found to remain at the labeled site for as long as 5~6 days.The period of net accumulation of HRP at the labeled sites was about 1 day.Thus,the best survival period would be roughly the time required for HRP to travel thefiber tract plus 1 day.Neurons of the red nucleus and the nucleus raphe pallidus differ greatly intheir morphology,physiology as well as biochemistry.The results in them however,were similar.This,in connection with observations on other nuclei,both anterogr-adely and retrogradely labeled,suggests that the rate of transport and the duration ofpreservation of HRP in the central nervous system are basically the same in differentneuronal systems.

用2~2.2公斤的白兔22只,在脊髓腰。段一侧注射一定量的 HRP,存活12小时至7日,在脊髓脑干长距离顺、逆运送的基础上研究了顺、逆行运送的速度及 HRP 在标记部位存留的时间。脑干中主要观察的顺行标记部位为背侧副橄榄核,逆行标记部位为红核及苍白中缝核。各核中顺行或逆行标记的出现及其消长过程相同,存活18小时后首先出现,2日后达高峰,7日后消褪殆尽。本研究得到以下的结论:1.HRP 被顺、逆行运送的速度相等,每日至少350毫米,属快速运送。2.标记的净积累时间约为1日,故最佳存活期大致相当按纤维长度计所需的运输时间加1日。3.HRP 在顺、逆行标记部位最多可存留~6日。4.HRP 在不同纤维系的运速及存留时间相同。

The topographical projections of the coronal gyrus (Co) onto the spinal trigeminal nucleus were investigated by using the method of the anterograde transport of WGA-HRP in the cat. The results obtained were as follows: 1. The anterior part of the Co projected to bilateral dorsomedial parts of the spinal trigeminal nucleus with a slight contralateral dominance. At the lower level of the medulla oblongata, however, its projections were only contralateral. 2. Projections of the middle and posterior parts...

The topographical projections of the coronal gyrus (Co) onto the spinal trigeminal nucleus were investigated by using the method of the anterograde transport of WGA-HRP in the cat. The results obtained were as follows: 1. The anterior part of the Co projected to bilateral dorsomedial parts of the spinal trigeminal nucleus with a slight contralateral dominance. At the lower level of the medulla oblongata, however, its projections were only contralateral. 2. Projections of the middle and posterior parts of the Co to the spinal trigeminal nucleus were primarily contralateral. In the subnucleus cauda- lis, the projections to its rostral half were found mainly from the middie part of the Co, they decreased in amount gradually and disappeared at the caudal level of the medulla oblongata. The posterior part of the Co sent fibers principally to the caudal half of the subnucleus caudalis. In the subnuclei oralis and interpolaris, the middle and posterior parts of the Cosent fibers to its medial part and lateral part, respectively. 3. In the subnucleus caudalis, the labelled terminal arborizations were found mainly in layers Ⅲ and Ⅳ, but in layers Ⅰ and Ⅱ a few labelled granules could also be observed.

The somatotopical pattern of the spinal projection to the lateral reticular nucleus (LRN) was examined in 16 rabbits. The anterograde transport of HRP method were used.1. Cervical, thoracic and lumbar segments all gave rise to small numbers of fibers projecting to bilateral lateral reticular subtrigeminal subnucleus (Lrs).2. Cervical, thoracic and lumbar projections to the LRN were bilateral but the cervical ascending fibers terminated predominately on the ipsilateral side. The lumbar ascending fibers projected chiefly to the contralateral side. The thoracic cord gave fibers to bilateral LRN. No significant difference could be seen between the two sides. There were certain overlapping among the distribution areas of the terminal branches from different parts of the cord.3. The spinal projections of the rabbit were predominately terminated in the caudal half of the LRN. It showed a somatotopical pattern. The cervical cord projected to the lateral 3/5 of the lateral reticular magnocellular subnucleus (Lrm) and its neighbouring part of the lateral reticular parvocellular subnucleus (Lrp). The thoracic cord projected to the medial 3/5 of the Lrm and its neighbouring part of Lrp. The lumbar cord gave afferents to the Lrp and its neighbouring part of Lrm.
