Adherens Junctions01:24

Adherens Junctions

5.0K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

科学领域:

  • 微生物学
  • 细胞生物学
  • 免疫学

背景情况:

  • 它与艾滋病毒的进展有关,并导致生殖器和尿路疾病.
  • 细菌的附着性对于Mycoplasma感染至关重要.
  • 负责M. penetrans粘附的特定蛋白质尚不清楚.

研究的目的:

  • 调查P35家族脂蛋白P38在M. penetrans与人类泌尿器细胞的粘附中的作用.
  • 描述复合P38 (rP38) 的粘合性.

主要方法:

  • 重组P38 (rP38) 的表达和净化
  • 西部斑点确认rP38的位置.
  • 使用rP38和M. penetrans对SV-HUC-1细胞进行粘附试验,抑制试验和竞争试验.

主要成果:
