Immunity to Viruses - NK Cells

Описание: Body responses to viruses both by Innate Immunity and Adaptive Immunity.

In this immunology video, you will get to know, the structure of the virus, the steps involved in viral replication, the role of cells of Innate Immunity and Adaptive Immunity such as T Cells and B Cells against viruses, and viral immunology.

▬ Immunity to Viruses ▬▬▬▬▬▬▬▬▬▬
The steps involved in virus replication in cells are:
♦︎ Attachment
♦︎ Entry
♦︎ Replication and Gene Expression
♦︎ Assemble
♦︎ Release

Antivirus Vaccine also utilizes the acquired immune response of the body.

▬ Innate and Adaptive Immunity ▬▬▬▬▬▬▬▬▬▬
Following are the cells of Innate Immunity to Viruses:
🟠 Natural Killer Cell
🟠 Interferons
🟠 Macrophage

Following are the cells of Adaptive Immunity against Viral diseases:
🔵 T Cell
🔵 B Cell
🔵 Antibodies

▬ Interferons ▬▬▬▬▬▬▬▬▬▬
Processes for induction of interferon genes are:
🟡 TLR-3 and TLR-7 Pathways
🟡 Sting Pathway
🟡 Jak-Stat Pathway

The antiviral immune response to Interferons is through:
🟠 MX Proteins
🟠 Oligoadenylate Synthase
🟠 PKR
🟠 Activate NK Cells

▬ Natural Killer Cells ▬▬▬▬▬▬▬▬▬▬
The antiviral role of NK Cells is by:
🔵 Perforin
🔵 Granzymes
🔵 Kill and Not to Kill Signals
🔵 FasL-Fas
🔵 Interferon Gamma

▬ Example of Innate and Adaptive Immunity Working Together ▬▬▬▬▬▬▬▬▬▬
Innate and Adaptive Immunity work together through ADCC.
