Question X. Which of the following can be considered as one of the innate immune mechanism entities and characteristics? Assess the following expressions and statements (1-3) concerning the innate immune-mechanism entities and characteristics as either factually correct (= “true”) or incorrect (= “false”):

1. Necessity of DNA rearrangements

2. Antigen Processing

3. Clonal deletion

Solution

1. Necessity of DNA rearrangements .

True genes of immunoglobulins and T receptors undergo DNA rearrangement in V(D)J recombination and occurs in the primary lymphoid organs. It involves somatic recombination that results in the supply of a variety of antibodiesor immunoglobulins (Igs) and T cell receptors (TCRs) found on B cells and T cells, respectively.

2. Antigen Processing .false. Play a role in adaptive immune response.

3. Clonal deletion adaptive immune response.
