ZD 7288 is an inhibitor of hyperpolarization-activated cyclic nucleotide-gated (HCN) channel [1].
The HCN channel is found in the sinoatrial node (SAN) and is permeable to both Na+ and K+. The HCN current exists in neurons under hyperpolarization of the cell membrane and plays an important role in neuropathic pain [1].
In CA1 pyramidal cells from Wistar rats, ZD 7288 inhibited T-type Ca2+ channel currents in a concentration-dependant way [2]. In neonatal rat facial motoneurones, ZD-7288 (0.1-10 μM) inhibited the hyperpolarisation-activated current with IC50 value of 0.2 μM in a time- and voltage-dependent way [3]. In CA1 pyramidal neurons, ZD 7288 (1-1000 μM) inhibited the hyperpolarization-activated current. However, ZD 7288 had no influence on long-term depression (LTD) of the CA3-CA1 synapse [4].
In rats with chronic visceral pain, ZD 7288 (50-100 nM) significantly inhibited abdominal withdrawal reflex (AWR) scores and electromyographic (EMG) responses. Also, ZD 7288 significantly increased pain thresholds. These results suggested that spinal HCN channels might play a critical role in chronic visceral pain [1].

实验需要请问有没有养THP-1细胞的同仁?能否寄一皿我,我在广州南方医科大学,不胜感激!
激光共聚焦的看活细胞皿哪里买呢
想问下各位大神,本人用皿养的PC-9GR细胞突然有大片飘起,也并没有成团状飘起,求解决方法?
如题~
已经基本养好了贴壁的原代细胞了,准备鉴定了,看到好多都在说细胞爬片的问题,我可以不做爬片直接在皿里操作吗?具体需要注意些什么呢?感谢各位大神
ps:大皿和6孔板里细胞密度、培养条件等等都几乎一样。
我看园子里有人提过类似的问题,但还没人给出答案,希望有经验或有想法的战友帮忙分析分析啊~谢谢!
同学说传代必须是一皿传多皿,一皿传一皿就不算传代~求高手指点~~
传代后5天,依然没有长满,怕影响活力,想传代和冻存,不知这样是否可以??
做细胞实验快半年了,一直都还挺顺的,这次五一放完假回来,复苏一支HK2,操作都跟以前一样,没想到出了好多问题:
冻存方法:包裹棉花直接-80℃过夜,第二天转移到液氮
冻存时间:1个半月前冻存的细胞,密度保证没问题,冻存前状态也好
复苏方法:液氮取出后37℃水浴,约2分钟溶解,加入6倍体积的完全培养基,800转离心5分钟,弃去上清,1ml完全培养基重悬,转移入培养皿(进口一次性塑料培养大皿),补足完全培养基,培养箱培养
第二天看细胞全都没贴壁,但是也没死,聚集成团装飘着,没有污染。不想重新离心加重机械损伤,就一直试试看的心态放在培养箱里养着了。又重新复苏一支,还是一样的结果,全飘着没贴壁。不死心,就往前面复苏的那一皿里直接加了1ml的血清,相当于18%的血清比例,过了一天去看,这下细胞都贴壁了。没有另外添加血清的那一皿就还是没贴壁。
另外还有一支以前复苏的HK2,也是一样的方法复苏的,那次复苏很好,细胞基本没什么死的,也都贴壁了,养在皿里状态也不错,但是拿来铺板就还是不贴壁,同样的培基(10%血清),铺板就一个不贴,皿里就都可以贴上。
求助各位战友:
1、复苏不贴壁是为什么?
2、增加血清比例能使复苏的细胞贴壁,这样的细胞是不是可以认为状态并不好,以后的培养是不是要一直这么高比例的血清?还是可以培养一段时间逐步减少血清比例?
3、仍然是10%血清,为什么铺板就不贴壁,而皿里的就没事?是不是铺板的时候也要增加血清比例呢?那在板里干预的过程中是不是要一直保持高比例的血清培养?
4、我的冻存及复苏方法是否有错?我觉得我的HK2从形态、生长速度上来说状态应该是不错的,而且我已经更换了全新的培基、血清和双抗,重新配置了完全培养基,不知道为什么会出现这种不贴壁的问题
拜托各位集思广益,细胞实验已经为了这个不贴壁的问题停滞快2周,心急如焚啊,拜托各位!
