  2. Viral entry - Wikipedia

    en.wikipedia.org/wiki/Viral_entry

    Viral entry via endocytosis. Viruses with no viral envelope enter the cell generally through endocytosis; they “trick” the host cell to ingest the virions through the cell membrane. Cells can take in resources from the environment outside of the cell, and these mechanisms may be exploited by viruses to enter a cell in the same manner as ...

  3. Viral replication - Wikipedia

    en.wikipedia.org/wiki/Viral_replication

    Entry, or penetration, is the second step in viral replication. This step is characterized by the virus passing through the plasma membrane of the host cell. The most common way a virus gains entry to the host cell is by receptor-mediated endocytosis , which comes at no energy cost to the virus, only the host cell.

  4. Viral life cycle - Wikipedia

    en.wikipedia.org/wiki/Viral_life_cycle

    To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where replication of the viral genome may commence.

  5. Receptor-mediated endocytosis - Wikipedia

    en.wikipedia.org/wiki/Receptor-mediated_endocytosis

    However, receptor-mediated endocytosis is also actively implicated in transducing signals from the cell periphery to the nucleus. This became apparent when it was found that the association and formation of specific signaling complexes via clathrin-mediated endocytosis is required for the effective signaling of hormones (e.g. EGF).

  6. Endocytosis - Wikipedia

    en.wikipedia.org/wiki/Endocytosis

    Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane , which then buds off inside the cell to form a vesicle containing the ingested materials.

  7. Active transport - Wikipedia

    en.wikipedia.org/wiki/Active_transport

    Endocytosis and exocytosis are both forms of bulk transport that move materials into and out of cells, respectively, via vesicles. [34] In the case of endocytosis, the cellular membrane folds around the desired materials outside the cell. [35] The ingested particle becomes trapped within a pouch, known as a vesicle, inside the cytoplasm.

  9. Viral transformation - Wikipedia

    en.wikipedia.org/wiki/Viral_transformation

    Figure 3: Examples of endocytosis. The process is similar in animal cells. In most cases, rather than viral DNA being injected into an animal cell, a section of the membrane encases the virus and the cell then absorbs both the virus and the encasing section of the membrane into the cell. This process, called endocytosis, is shown in Figure 3. [5]
