概括
这项研究详细介绍了一名患有3型神经状脂症 (CLN3) 的日本患者,突出了早期视力障碍和随后的全身衰退. 清空淋巴细胞和视网膜退化可能为该人群中CLN3提供关键的诊断线索.
科学领域:
- 遗传学和罕见疾病.
- 神经科学是一个神经科学.
- 眼科医生 眼科 眼科
背景情况:
- 神经神经状脂症 (NCL) 包括罕见的溶酶体疾病.
- 一种特定类型的CLN3与溶酶体跨膜蛋白基因的突变有关.
- 关于日本CLN3患者的数据有限,需要进一步临床表征.
研究的目的:
- 报告一个患有CLN3.3的日本患者的临床过程和遗传发现.
- 在日本人口中识别CLN3的潜在早期诊断标志物.
主要方法:
- 一个17岁的日本男性患有CLN3.3的病例报告.
- 临床评估包括眼科评估,神经检查和连续MRI.
- 整体外基因组测序和桑格测序用于遗传确认.
- 对430名CLN3患者的文献综述.
主要成果:
- 患者在7岁时出现了视网膜色素炎,随后出现了发作,发育回归和大脑/小脑缩.
- 基因分析揭示了复合异质合体的CLN3变体:c.[295-2A>C];[178_180delinsACATCCTTAGCCACAAGAG].
- 观察到血液异常,包括淋巴缺血和真空淋巴细胞,与对430名CLN3患者的审查形成鲜明对比.
结论:
- 这位日本患者的CLN3表现为视力障碍,系统性恶化前7-8年.
- 视网膜退化和真空化的外周淋巴细胞可能成为日本人的CLN3早期诊断指标.

Lysosomal Hydrolases
4.4K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Secondary Lymphoid Organs
8.8K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Primary Lymphoid Organs

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...
