Which оf the fоllоwing types of immunity is more pаthogen specific?
Immunоdeficiency diseаses аrise when individuаls lack оne оr more components of their immune system, and are identified by an individual’s history of persistent or recurrent infections. Some genetic defects (mutations or small deletions) can cause profound defects in an immune cell population; alternatively, in some cases, such small defects occur that there is no visible effect on immune responses, just a decrease in the diversity of TCRs and BCRs generated. The diagram in the Figure below shows simplified versions of the immunoglobulin heavy chain locus, the T-cell receptor beta chain locus, and the locus encoding the RAG-1 and RAG-2 recombinases. For the sake of this question, imagine that these diagrams represent all of the gene segments present in the immunoglobulin heavy chain and T-cell receptor beta chain locus. You now analyze five individuals, each of which has a single inactivating mutation in a region of one of these three loci. These mutations are each indicated by a red ‘X’ in the Figure below, and are numbered 1–5. Which individuals would result in an immunodeficiency due to not generating functional TCRs and/or BCRs? Select all that apply.
