- 遗传学 是一个遗传学.
- 病理学 病理学 病理学
背景情况:
- 变性蛋白酶敏感性隐性病 (VPSPr) 是一种罕见的,非典型的隐性病.
- 目前,VPSPr被归类为零星的子疾病.
研究的目的:
- 为了调查VPSPr.的潜在遗传原因.
- 分析来自VPSPr患者的PRNP非编码区域和外基因组测序数据.
主要方法:
- 在VPSPr患者 (N=67) 的外序列化.

Amyloid Fibrils
9.9K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Subviral Agents
113
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
