Lecture´s Description

Introduction
In this lecture ´´Cell-Cell Junction´´ is explained. Section one is about ´´Introduction´´. Initially, educator talks about extracellular matrix. Alongside, gives information about two main ways in which animal cells are bound together. Likewise, cell junctions are elaborated comprehensively. Educator also tells that transmembrane adhesion proteins link the cytoskeleton to extracellular structures.


Types
Section two is about ''Types''. Educator starts this section by explaining anchoring junctions. After that cadherins are elaborated. Then homophilic adhesion is pursued. Following this, organization of developing tissue is discussed in detail.


Cadherin Based Cell Junctions
Section three is about ''Cadherin Based Cell Junctions''. Educator begins by talking about epithelial–mesenchymal transitions. Then light is shed on cadherin-cytoskeleton interaction. Furthermore, mechnotransduction in adheren junctions is thoroughly explained by the educator.


Desmosomes and Tight Junctions
Section four is about ''Desmosomes and Tight Junctions''. Primarily in this section, structure of desmosomes is discussed. After that importance of desmosomes is highlighted. Following this, tight junctions comes under consideration. Educator notify that epithelium of the small intestine provides a good illustration of tight-junction structure and function.


Gap Junctions and Adhesion Proteins
Section five is about ''Gap Junctions and Adhesion Proteins''. At first, structure of gap junctions is pursued in this section. Then educator talks about plasmodesmata. This is followed by elucidation of selectins. Concluding comments are given on immunoglobulins.
