概括

洞穴性鼻 (CS) 壁中的原蛋白差异解释了为什么垂体腺瘤会比侧面壁 (LW) 更频繁地侵入中间壁 (MW). 与年龄相关的原成分变化有助于这种脆弱性.

科学领域:

神经解剖学是一个神经解剖学.
历史学历史学历史学
生物化学生物化学

背景情况:

垂体腺瘤经常侵入洞穴鼻腔 (CS),主要突破中间壁 (MW).
在CS中介壁 (MW) 和侧壁 (LW) 之间的结构差异尚未得到充分理解.
调查原蛋白分布可能会阐明MW特定侵袭的基础.

研究的目的:

为了分析 I-IV 类型的原蛋白在人类胎儿和成人洞腔鼻腔 (CS) 样本中的分布.
为了将原蛋白亚型的差异与CS中间壁 (MW) 和侧壁 (LW) 的结构特征相关联.
探索原组合在脑下垂体腺瘤偏好入侵中壁 (MW) 中的潜在作用.

主要方法:

使用跨和内镜方法剖析22个成年人和2个胎儿洞腔鼻 (CS).
免疫组织化学分析 I-IV 类型的原蛋白,取取 CS 中间壁 (MW),侧壁 (LW),前壁和隔膜腰部的样本.
对胎儿与成年标本以及不同CS壁之间原蛋白分布的比较.

主要成果:

I,III和IV类型的原体在成人和胎儿的CS壁中显示出不同的分布模式.
I型原蛋白在成年MW中存在很弱,在成年LW和胎儿CS中不存在.
在成人MW中发现了III型原蛋白,部分在LW中发现,而IV型原蛋白在成年人体内不存在,但存在于胎儿体内.

结论:

洞穴鼻腔 (CS) 原蛋白的组成随着年龄的增长而发生显著变化,I型和III型原蛋白增加,IV型原蛋白减少.
结构上的差异,特别是中间壁 (MW) 和侧壁 (LW) 之间的原蛋白含量,可能解释了MW对垂体腺瘤入侵的更高易感性.
矩阵金属蛋白酶 (MMP) 依赖的降解途径可能参与观察到的MW入侵模式.

The Pituitary Gland

The Pituitary Gland

The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
