Thank you for uploading this! You're video's have been a big help in understanding immunology.
Thank you so much doctor!! Ur video was really very helpful and it cleared all the concepts.
Thank you so much for sharing these videos. They are extremely helpful during my studies. You have a gift of teaching!
+Melody Agre thank you! We have more lectures drbeen.com.

Thank You very much for the lecture Doctor! Now I got it :) It was a really big help for Immunology final next week. I'm gonna watch Your other lectures too!
+Mándy Dávid good to know. We have other systems uploaded on the drbeen.com.
an excellent explanation of tumor immunity.. I will recommend it to my students!!
great series, I'm not working in medical field, but I found this very informative and easy to follow.
Good to know James Parus. Even while recording these lectures for the healthcare professionals or students the intent was to make the content easy to digest for everyone.

thanks for the grate lecture.
there is one of the more very very important way of the cancer cells supress the t cells
very well explained
Thank you a lot..
Thank you for this presentation. Do you know any knowledge on anti-leukaemia immune surveillance? Several of the tumour markers presented on solid tumours are not expressed on leukaemic cells.
Best video best explanation
thanks, doctor it was helpful!
thank you ♥️♥️
Marvellous... Sir...👌
Hi, do you have any references for the types of antigens presented on a tumor cell?
Fantastic!
cool. Check drbeen.com for more lectures.
MashaAllah this video so helpful for me and my friends
Thank u sir!
Thanks
Thanks a lot sir , very useful.
My pleasure. Enjoy!
thanks DR but what the roles of the tumor infiltrating lymphocytes
Really Helpful :)
sir could you please give a link for lecture related to FAS/FASL/CD98L, TNF between tumor cell and Cytotoxic T lymphocyte.
hello sir can u explain in detail how MHC-1 express tumor supprssar gene on the surface.
wonderful sir helpful lecture!
+muhammad tayyab thank you sir!
Hi Dr Is there any immunotherapy available for EBV induced cancer? igg level for ebv > 600
thanks a lot sir.......
Welcome. Check drbeen.com for more lectures.
Why would the product of tumour suppressor genes be displayed on MHC 1 in cancerous cells, but not normal cells? Surely the TS gene would be expressed in normal cells anyway, so would still be detectable on MHC-1?
THANK YOU (From Dominican Republic.)
Welcome from US :-)
thank you !!!
Welcome!
tremendous sir......
Thank you. Find more lectures here: www.drbeen.com/catalog

Good to hear. Study well and be the best doctor!
Thnx..:)
good video, this include mitosis?
Hello Dr. Mobeen. Thanks for the great lecture.
There is one more very very important way the cancer cells suppress the T-cells.
The cancer cells over express the enzymes IDO (Indoleamine 2,3-dioxygenase) or TDO (Indoleamine 2,3-dioxygenas). These enzymes deplete the tryptophan concentration in the tumor micro-environment, thus reducing the tryptophan availability to T-cells and hence reduce their survival and growth.
Thank you for sharing. Good point.
Tumor suppressor genes are present every cell ...and actually it's growth suppressor genes ..these are genes which regulate growth.
But when they are mutated tumor suppressor genes are only in cancer cells
Thanks ...you explained nicely
my doctor , tomorrow is my final exam in immunology , and i am sure i will get very good result coz of your fantastic explanation :))
Good luck Yasser! Glad explanation is useful.
Hey sir? Wanna ask for a fovour!
Have you given some videos on neoplasia?? I actualy need those😢😢
Not yet. Planning for it soon.
gooooood good
Tumor suppersor gene most common RB produce gene on chromosome no.13 right sir???
+muhammad tayyab I think so!
In which lecture do you talk about fas/fasL killing mechanisms? Like what you mentioned at 13:34
Joshua He - listen to the NK cell lecture. Also the initial big picture lectures have the Fas-FasL discussion too.
what is maylance ? is that company ?? or what ?? interesting job you are doing sir .
+Venkteshwar Singh ranout yes it is a company. I am currently running drbeen corp.
Thank you
Welcome!
Sir, Start new session
How does the macrophages would kill the tumor cells? using what mechanism?
Pattern recognition. Recognition of abnormal proteins. Recognition of lack normal proteins, etc. Mostly the tumor cells get caught by NK cells due to the lack of MHC1 expression.
Hi
Tyraminase or tyrosinase
Tyrosinase not tyraminase
Dr. sab looking handsome ..!!
+Venkteshwar Singh ranout thank you!
Its true that he is handsome and nice to listen to he he
hahaha
sounds like a macrophage deficiency
i should just pay my uni fees to you instead of my own lect
