Question $3$ options:

$12345678910$

Transmembrane protein whose extracellular domain containing leucine$-$rich repeat $($LRR$)$ regions recognizes pathogen$-$associated molecular patterns $($PAMPs$).$

$12345678910$

Transcription factor held in the cytoplasm in an inactive form in complex with an inhibitor protein and released upon signaling from receptors of innate and adaptive immunity.

$12345678910$

Expressed in centroblasts; genetic deficiency causes one form of hyper$-$IgM syndrome.

$12345678910$
