Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...
Inside cells, there exists an extensive system of canals known as the endoplasmic reticulum (ER), which consists of membrane-encased tubes that are partially broken down as needed—for instance in case ...
You probably learned about organelles, those little “organs” inside cells that form compartments with individual functions.
The Visking tubing is the selectively permeable membrane. Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated ...
2024年9月19日,中国科学院上海药物研究所甘勇研究员、俞淼荣副研究员与浙江大学胡国庆教授团队合作在Nature Nanotechnology上在线发表了题为“Direct Cytosolic Delivery of siRNA via Cell Membrane Fusion Using Cholesterol-Enriched Exosomes“的研究论文。
Research shows mitochondria form distinct subpopulations under nutrient stress, revealing survival mechanisms in cancer cells ...
These membranes, composed of flexible lipid bilayers, can reshape and remodel themselves during processes like cell movement, division, and molecular trafficking. Until now, it was commonly assumed ...
This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...
镉(Cd)是一种十分有害的重金属元素,以其较高的移动性和较强的生物毒性著称 [1],严重威胁生态环境和人类健康。Cd能通过植物进入食物链,最终在人体内累积并诱发多种疾病 ...
Researchers from the Heart Center of the University Medical Center Göttingen (UMG) led by Priv.-Doz. Dr. Sören Brandenburg ...
引言细胞是生命活动的基本单位,内部的各个区域通过细胞器实现其特定功能。在这些细胞器中,过氧化物酶体(peroxisome)扮演着不可或缺的角色。自20世纪60年代被首次发现以来,过氧化物酶体的研究不断揭示其在细胞生理中的重要性【1】。它不仅在脂质代谢 ...
