Type 2 hypersensitivity

Type 2 hypersensitivity - This immunology lecture video explains about type 2 hypersensitivity reactions that is caused by allergen and the response is mediated by immunoglobulin E or antibody E.

Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC) is a mechanism of cell-mediated immune defense whereby an effector cell of the immune system actively lyses a target cell, whose membrane-surface antigens have been bound by specific antibodies. It is one of the mechanisms through which antibodies, as part of the humoral immune response, can act to limit and contain infection. Classical ADCC is mediated by natural killer (NK) cells; macrophages, neutrophils and eosinophils can also mediate ADCC. For example, eosinophils can kill certain parasitic worms known as helminths through ADCC. ADCC is part of the adaptive immune response due to its dependence on a prior antibody response.

Thank you for watching type 2 hypersensitivity reaction lecture.

[@freecheese4143]

The BEST explanatiion I have ever heard- college professors included !

[@Invincible-x7y]

Very helpful sir I'm a para medical student your lecture is much better than some of my lecturer

[@sayeedasultana4564]

Thank you all your lectures are excellent. You work very hard to simplify this complicated subject ,also make them interesting

[@shomusbiologyofficial]

Thank you so much for appreciating my efforts

[@malihamannan5892]

you didnt explan the basic mechanism of type-2 hypersensitivity reaction,you only explained about the example of this hypersensitivty

[@thutran5429]

muhammad imran antigen and antibody react and activate the compliment. one of the consequences of activation of the compliment is cytolysis- the cell get destroy

[@saloninema9981]

I love ur teaching tect ..ur tone while u do conversation between teaching is so connecting 👏👏👏😘😘😘👌👌

[@shomusbiologyofficial]

Thank you for appreciating my efforts

[@saloninema9981]

Sir it's god grace that I found ur Chanelle otherwise sitting on this small place I wouldn't be able to continue my dream...nd I also want to be a part of ur online coaching classes for CSIR UGC net after my graduation

[@payelkarmakar9941]

Thank you Sir for explaining so simply

Awesome videos sir... u make pharmacology easy....tysm sir for making such great video...

[@siddharthr.kathiriya8268]

Keep it up 👍
Very Helpfull to Me.

[@gautamsinha8086]

Best teacher ever.......... Respect yu sir

[@shomusbiologyofficial]

Thank you so much

[@gautamsinha8086]

it's my pleasure

[@asthapandey7166]

Thanks a lot . For your time 💐🌸💮.

[@shomusbiologyofficial]

You're welcome. Glad to hear that you're getting benefit from my lectures

[@kanguernoorani4091]

Please correct it , the antiA and antiB are not expressed on the surface of RBC they are present in the plasma.

[@ehsanulhaq5679]

explanation is only about blood disease , but did not explain about other disease and mechanism of type 2 in detail

[@learnwitharoosawaheed]

Perfect

[@facts450]

Sir please explain fever topic, etiology, mechanism ect

[@shomusbiologyofficial]

Sure

[@mayuripawar4851]

very nice

[@lilpeep2356]

Thank you so much

[@shomusbiologyofficial]

You're welcome

[@entesalinkunju6855]

Are the antibodies present in the plasma or inside the RBC?

[@onyekanwachukwu4676]

you are the best

[@shomusbiologyofficial]

Thank you. Do subscribe.

[@SanDhyaa1212]

Too easy to understand ur lecture

[@shomusbiologyofficial]

Thank you

[@anoshakhaliq1470]

Nice......keep it up

[@shomusbiologyofficial]

Thank you

[@entertainmentclips58]

best teacher

[@BowingBliss]

surface antigens are endogenous or exogenous?

[@MonuYadav-rs9gy]

Excellent sir..

[@JudithTheROSE]

What determines the blood type

[@shomusbiologyofficial]

The sugar and protein coating present in rbc surface

[@noorfalak6341]

Can lymph transfer from one person to another cause type 2 hypersensitivity?

[@artigangarekar984]

Thank you sir

[@smitakunwar9897]

Great job

[@ayisuwarayi8947]

the basic principal of HR type 2 : the antibody bind to surface antigent on cell, then this antigent-antibody complex will induce complement activation and phagocytosis. actually which one that can cause disease or death??? the agglutination or the hemolysis??? i am confused

[@HebaS996]

Thank you so much ❤❤❤❤

[@shomusbiologyofficial]

You're welcome

[@RohitYadav-cr6rk]

Hey ghis is not topic of blood transfusion its hypersensitivity

[@samichaudhary3293]

Thnku sir... It was very simple way to understand the concept of hypersenstivity type 2 reaction.. But sir how we will deal with that mother which u discussed later and death of baby how we prevent from this

[@kanguernoorani4091]

First of all Rh negative lady should not marry Rh positive man if possible so as to avoid the possibility to have an Rh positive faetus , secondly injection Anti D is given to mother during pregnancy to neutralise the Rh antigen if any that enters mothers circulation from foetus. If husband is also Rh negative then no problem as there will be no chance to have Rh positive faetus in that case .

[@hanumansankhala4154]

Sir Kya ye sirph 1st pregnancy me hi ho Sita h Kya and Kitna time lgta h anti rh bnne me more than 9 month

[@learntogether8900]

Sir, cn you explain mechanism of cell signaling ?

[@shomusbiologyofficial]

It's explained in a separate video

[@iffatazim6722]

Sir pls make video of this topic in hindi

[@mohamadsubhanbhat7166]

great!!!!!

[@akkidahe8935]

how is anti b produced in blood of person having blood group a.. when he ws not even having exposure of antigen b

[@sanjithkarthikeyan3023]

Because the synthesis of anti A and anti B antibodies are under genetic control and doesn't need antigenic stimulation. These appear in the infant's serum by 6 months of age.

[@shuklaswadha5375]

what if fetus is Rh negative and mother is Rh positive???

[@francismendy9687]

no reaction will occur

[@sandhiyakumaresan4589]

Francis Mendy ---- how?

[@subarnaray8155]

And also what happens when the mother is rh positive and baby is rh negetive

[@kanguernoorani4091]

Nothing will happen bcz the immune system of foetus is not mature enough to produce anti Rh .

[@shikhasharma8217]

Sir y vala transfusion vala vedio aap Hindi m bnayye plz

[@shomusbiologyofficial]

Okay

[@subarnaray8155]

In case of erythrobhlastosis foetalis , the blood of the foetus never mixes with the mothers blood , so how the anti rh even produced ? since the rh antigen is never coming in contact with the blood of the mother

[@govin4675]

Subarna Ray : normally it doesn't comes any contact between the blood of mother and child (during the time of pregnancy). Only at the time of delivery comes to contact, not a large amount but enough to activate the Anti Rh production.

[@medicinebaghdad4706]

Bravoooo

[@IslamKhan-pb8vm]

Thoda hindi m v btaya kriye sir

[@BalaBiologyWorld]

DADA really tremendous......

[@FreeFire-vc7vo]

Qt confusing

[@sazlanaraheem4455]

Unwanted talks rather hypersensitivity 2 ...completely nonsense...
