Introduction to Virus

1.8K
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

Viruses of Archaea

528
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Active versus Passive Immunity01:31

Active versus Passive Immunity

11.0K
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.
Active Immunity
Active immunity refers to the resistance one develops...

Area of Science:

  • Immunology
  • Oncology
  • Virology

Background:

  • Early research viewed the immune system as an obstacle to oncolytic virus (OV) therapy.
  • Recent evidence highlights the immune system's critical role in OV efficacy, reversing previous assumptions.

Purpose of the Study:

  • To review the pivotal role of innate and adaptive immunity in oncolytic virotherapy.
  • To explore rational combinations of OVs with other immunotherapies for improved therapeutic outcomes.

Main Methods:

  • Literature review on the interplay between oncolytic viruses and the immune system.
  • Analysis of current research on immune responses to OVs.
  • Examination of combination strategies involving OVs and immunotherapy.

Main Results:

  • The immune system is essential, not detrimental, to the success of oncolytic virotherapy.
  • Both innate and adaptive immune responses significantly contribute to the anti-tumor effects of OVs.
  • Combining OVs with other immunotherapies shows promise for enhanced treatment efficacy.

Conclusions:

  • The immune system is a key facilitator of oncolytic virotherapy, shifting the paradigm from foe to friend.
  • Harnessing immune responses alongside OV treatment is crucial for maximizing therapeutic potential.
  • Strategic integration of OVs with immunotherapy offers a promising avenue for advancing cancer treatment.
