Virology Lectures 2021 #14 - Adaptive Defenses

The adaptive immune system, in contrast to intrinsic and innate defenses, is tailored to the pathogen and has memory. In this lecture we examine how B and T cells are instructed by the innate immune system, how antibodies and cytotoxic T cells are made, and their roles in preventing and resolving virus infections. Includes explanations of rapid tests for SARS-CoV-2 antibodies and antibody therapy for COVID-19 patients.

– Who Am I? –

I’m Vincent Racaniello, Earth’s Virology Professor.

I’m also a professor of virology at Columbia University in New York. I’ve been doing research on viruses since 1976, and teaching virology in classrooms and online since 1999. On this YouTube channel I share videos of my lectures, podcasts, and more.

New videos are uploaded multiple days a week.

How brilliant people throughout the decades figured all of this out is truly remarkable.

[maxplank]

Clear concise and one of the few science sites where the graphics are easily visible on smartphone

[gleeful]

Love virology b/c of you sharing your class! Thank you so much for sharing this information!

Igm is happening at the same time as IGG, , I had thought IGM preceded IGG and IGA. Interesting lecture. I didn't catch that last year. The work that Professor Vincent Puts into these lectures every year really helps illuminate various aspects, makes a difference.

Absolutely love the level of detail, imagery and explanations. The innate immunity class and this class are me favourite. Can we please talk in depth about Germinal Centres!

[thierryfucus]

Great Teaching videos. I wish we have more info on how immunity, Allergy share our bodies. Autoimmune and allergic Diseases. You can post credible links.

This finally after about 4 months. I have been trying to understand this

[jorhjim]

Dr Vincent this has been a good explanation learning our defenses and the coronavirus respond in humans.

[Старкрафткомедия]

so if human cytomegalovirus (hcmv) dampens mhcII transcription (which is what all antigen based immune response depends on), does that mean people carrying hcmv (which is like 50%+ people) have compromised immunity against all infections that need mhcII antigen based defenses?

[PhysicsNative]

Do not agree with the statements that innate immune responses have no memory, and that inflammation is necessary for a functional immune response. Obviously there is so much we don’t know about natural immunity, and not enough detailed inquiry into this area.

I'll need repetition that's if this miracle persists
