When T cell finally handshaked the B cell that was so dramatic i cried

This material is gold.

Damn the immune system is insane! Fascinating video

[@mohamedbashir2689]

Thanks body

[@waadfarhan3168]

What a Great video ! it's very helpful , Thanks a lot.

[@chia9785]

The best video for this topic!

Great explanation!

[@Fido-vm9zi]

Very interesting. Thank you!

[@zanecosgrove4820]

Wow, thank you

[@ozeirkazemi]

How do the denderitic cells present viral Ag on its MHC class II to activate CD4 Th cells?

[@aqdusshaikh1306]

By the endocytic pathway .

[@nainakhan4157]

Same question

[@michelle_sea_view]

Thank you

[@rafaelcampozana]

that will be useful in my pathology final exam

[@jvnebugged]

hope you passed it

Nice vid

A lot of information here, but you did not mention when a fever occurs during this process. Is the fever part of the innate immune response or the adaptive immune response? Also, specific to coronavirus family members, when does lung congestion come in?

[@RunningFlan]

Fever occurs during the innate immune response. There are a number of ways that fever can be triggered but one path would be: 1. Cells that have been destroyed by viruses release damage-associated molecular patterns (DAMPs) 2. Sentinel cells become activated by damage-associated molecular patterns and begin synthesising a chemical called interleukin-6 (this takes hours to synthesise) 3. Interleukin-6 acts on the hypothalamus which reacts by raising the core body temperature (causing fever)

So fever heats up body to Kill infection

How did CD8+ become activated?
