We have developed several non-genetic cell membrane modification approaches to functionalize cell membranes, such as physical attachment and chemical modifications. Through these functionalization approaches, the original properties of the natural cell membranes could be maintained while adding desired functions In order to move molecules from the lumen into the cells and from cells into the blood or vice versa, channel proteins and carrier proteins are present on the apical and basolateral surfaces of the epithelial cells. The channel proteins allow small ions to move across the cell membrane. These are often gated to open and close in response to a certain stimulus Phase changes of cellular membranes can be rather complex due to the many constituents of the membranes, which also differ considerably in composition among cell types [10,13,18,19]. Further, rapid cooling should also lead to different membrane configurations than slow cooling, since it does not allow the membranes to reach their thermodynamic equilibrium state Cell junctions are the contact points between plasma membrane and tissue cells. Some examples of the major types of cell junctions: tight junctions, gap junctions, desmosomes and hemidesmosomes. Tight junctions are transmembrane proteins fused on outer plasma membrane. Gap junctions connect the cytoplasm of two cells and allow for the passage.

Post-translational modification (PTM) refers to the covalent and generally enzymatic modification of proteins following protein biosynthesis.Proteins are synthesized by ribosomes translating mRNA into polypeptide chains, which may then undergo PTM to form the mature protein product. PTMs are important components in cell signaling, as for example when prohormones are converted to hormones Transport of materials across the plasma membrane is essential to the life of a cell. It also essential to maintain equilibrium of cell Certain substances must move into the cell to support metabolic reactions.

Introduction. Cell membranes are composed of various lipid, protein, and carbohydrate compounds. These membrane components dynamically interact with each other to regulate cell cycles and communications (Lee, 2003; Contreras et al., 2011; Varshney et al., 2016; Sezgin et al., 2017).Based on the affinity and duration of these interactions, there are two types of membrane interactions: strong. The endoplasmic reticulum. The endoplasmic reticulum ( ER) plays a key role in the modification of proteins and the synthesis of lipids. It consists of a network of membranous tubules and flattened sacs. The discs and tubules of the ER are hollow, and the space inside is called the lumen The cell membrane is a structure that is fluid-like in movement.

The fluid mosaic model of cell membrane was proposed in 1972 by S.J. Singer and G.L. Nicolson. According to this model, the cell membranes have been visualised as mosaics of lipids and proteins. The lipids are thought to be arranged primarily in a bilayer in which peripheral and integral proteins are embedded to varying degrees (Fig. 2.5) A cell's plasma membrane defines the boundary of the cell and determines the nature of its contact with the environment. Cells exclude some substances, take in others, and excrete still others, all in controlled quantities. Plasma membranes enclose the borders of cells, but rather than being a static bag, they are dynamic and constantly in flux Porins are proteins in this cell membrane that allow substances to pass through the outer membrane of Gram-negative bacteria.

The cell membrane is the outer covering of a cell within which all other organelles, such as the cytoplasm and nucleus, are enclosed. It is also referred to as the plasma membrane. By structure, it is a porous membrane (with pores) which permit the movement of selective substances in and out of the cell cell - cell - Cellular response: The binding of chemical signals to their corresponding receptors induces events within the cell that ultimately change its behaviour. The nature of these intracellular events differs according to the type of receptor. Also, the same chemical signal can trigger different responses in different types of cell Therefore a protein that is eventually found on the outer surface of the cell membrane will have been inserted into the lumenal surface of the ER membrane to begin with.

Lipid peroxidation can be described generally as a process under which oxidants such as free radicals attack lipids containing carbon-carbon double bond(s), especially polyunsaturated fatty acids (PUFAs). Over the last four decades, an extensive body of literature regarding lipid peroxidation has shown its important role in cell biology and human health. Since the early 1970s, the total. After translocation across the membrane, GPI anchored proteins are bound to the cell membrane by the insertion of the phosphatidylinositol lipid moieties into the hydrophobic lipid bilayer. Once the GPI anchored protein has been produced, the Man 3 -GlcN oligosaccharide core may undergo additional glycosylation modifications during secretion. In viruses such as HIV, this modification (sometimes called maturation) occurs after the virus has been released from the host cell. Viruses can be released from the host cell by lysis, a process that kills the cell by bursting its membrane and cell wall. This is a feature of many bacterial and some animal viruses Plasma membrane. To ensure each cell remains separate from its neighbor, it is enveloped in a special membrane known as the plasma membrane. This membrane is predominantly made of phospholipids.
