Establishing an Adult Mouse Brain Hippocampal Organotypic Slice Culture System that Allows for Tracing and Pharmacological Manipulation of ex vivo Neurogenesis

[Abstract]  

The function of the hippocampus depends on the process of adult hippocampal neurogenesis which underpins the exceptional neural plasticity of this structure, and is also frequently affected in CNS pathologies. Thus, manipulation of this process represents an important therapeutic goal. To identify potential strategies, organotypic adult brain slices are emerging as a valuable tool. Over the recent years, this methodology has been refined and here we present a combined protocol that brings together these refinements to enable long-term culture of adult hippocampal slices. We employ a sectioning technique that retains essential afferent inputs onto the hippocampus as well as serum-free culture conditions, so allowing an extended culture period. To sustain the neurogenic potential in the

[Abstract]  An easily induced preclinical trigeminal neuropathic nerve injury model is described here for the study of chronic pain, the model acronym FRICT-ION (Foramen Rotundum Inflammatory Constriction Trigeminal InfraOrbital Nerve). In patients, neuropathic pain is thought to be related to vascular alignment or multiple sclerosis along this small trigeminal nerve branch (V2) innervating the maxillary teeth and middle third of the face. With no detectable outward physical signs, the FRICT-ION model is ideal for blinded studies. The acronym FRICT-ION applied relates to the persistence of the trigeminal neuropathic pain model likely due to sliding irritation with normal chewing in the mice. A step-by-step method to induce the mild ...

Optic Nerve Crush in Mice to Study Retinal Ganglion Cell Survival and Regeneration

[Abstract]  In diseases such as glaucoma, the failure of retinal ganglion cell (RGC) neurons to survive or regenerate their optic nerve axons underlies partial and, in some cases, complete vision loss. Optic nerve crush (ONC) serves as a useful model not only of traumatic optic neuropathy but also of glaucomatous injury, as it similarly induces RGC cell death and degeneration. Intravitreal injection of adeno-associated virus serotype 2 (AAV2) has been shown to specifically and efficiently transduce RGCs in vivo and has thus been proposed as an effective means of gene delivery for the treatment of glaucoma. Indeed, we and others routinely use AAV2 to study the mechanisms that promote neuroprotection and axon regeneration in RGCs following ONC. Herein, we describe a step-by-step protocol to ... [摘要]  [摘要 ] 在青光眼等疾病中,视网膜神经节细胞(RGC)神经元无法存活或无法再生视神经轴突,这是部分视力丧失的原因,在某些情况下,甚至是完全的视力丧失。视神经挤压术(ONC)不仅可以作为创伤性视神经病变的一种有用模型,而且还可以作为青光眼损伤的有用模型,因为它类似地诱导RGC细胞死亡和变性。腺相关病毒血清型2(AAV2)的玻璃体内注射已被证明特别地和有效地转导视网膜神经节细胞在体内和已因而被提出作为基因递送用于治疗青光眼的治疗的有效手段。确实,我们和其他人常规使用AAV2来研究促进ONC 后RGC中神经保护和轴突再生的机制。本文中,我们描述了分步操作的方案,以测定AAV2介导的转导和ONC损伤后小鼠中RGC的存活和再生,包括1)玻璃体内注射AAV2病毒载体,2)视神经挤压,3)霍乱毒素B (CTB)标记再生轴突,4)视神经清除,5)视网膜平面免疫染色和6)定量RGC存活和再生。除了提供执行此协议所需的所有材料和程序详细信息之外,我们还强调了它比其他相似的已发表方法的优势,并提供了有用的技巧以确保其在任何现代实验室中都能如实复制。
