Answer 1

Solution selated to Immunology The markers on Hello , in here we are going to discuss about questions surface pathogens Pathogen Assouated Protein. These can be the suone of the pathogen. These protein are sometimes called as PAMP Seen on is Sind to the PRRI of 0 other Therefore ore option optom (C) PAMPS ph correct. are wrong, because others are receptors options are which helps to recognize uze the the pathogen and binds to the PAMPS.

ognition prodein which Fc o PRR is Pattern Rewoo recognizes PAMP. Ther is Toll like receptors And to receptors can be seen in some immune cells like B-cells, dendritie cells, cells ete. • Therefore option (C) PAMPS is is correct . NK th

ine will o The in the Thymus completes their den 12) the Freell that interacts with self antigen thymus undergo Apoptosis of rell. Flymphoute development In the Thymus, they get matured and release oso the Fall which interacts with the sell w Thymus will be a self reactive T-cell to the Tell inside the oso option (1) apoptosis. Thymus itself reactive have to be remove to prevent autoimmune disorders. Th antigen othese ܂ ܃ ܕ self T-cells

other options are get wrong Because these immature Frells doesn't activated, or extravasation is not happen. And that get destroyed. oso option (A) is correct. 13) Most the that enter the Thymus will the will undergo apoptosis. Only few of enter into another step ce production T cell markers like Ter, CD3; CD4 02 188 and CD2 of ce of .

And moute is to maja future autiome differentiate into I helger alls of i ulotoxic cell- for a thymoute oso option (as Offerentiation into Tc cell is corrent. Thymus Thymoute. so option so option cal is wrong. Apoptosis the cell, but the future outume will be The activation of B-cell is not related to and ouur un many of Po or Ter cell formation.

1G ) The innate immune is the in born immune includes the correct the options, o that contain System responses. The physical physical barrier, chemical barrier inflammatory barriers and thagousten barriers are Among option the cells that involved in innate immune response option (B). Neutrophils, maurophages, The cells that are involved in innate immune response Basophils, neutrophils, marrophages, Nk cells, mast es NK ells. are cells, ate :

other options options are we Because in in other wrong. options Trells and B-cells are included. Actualy B-ulls and Fields are not involved in innate immune response are included in Adaptive responses Thank you immune they Therefore option (B) is correct.

In case of any query please comment. If you have liked the solution then please THUMBS UP.

Due to time limit I only answered first 4 questions And according to our rules first 4 have to be answered..so I hope you understand my answers.

Thank you
