Positive selection occurs through antigen-independent signalling involving both the pre-BCR and the BCR. [9] [10] If these receptors do not bind to their ligand, B cells do not receive the proper signals and cease to develop. [9] [10] Negative selection occurs through the binding of self-antigen with the BCR; if the BCR can bind strongly to self-antigen, then the B cell undergoes one of four fates: clonal deletion, receptor editing, anergy, or ignorance (B cell ignores signal and continues development). [10] This negative selection process leads to a state of central tolerance, in which the mature B cells do not bind self antigens present in the bone marrow. [8] Autoimmune disease can result from abnormal B cell recognition of self-antigens followed by the production of autoantibodies. [31] Autoimmune diseases where disease activity is correlated with B cell activity include scleroderma, multiple sclerosis, systemic lupus erythematosus, type 1 diabetes, post-infectious IBS, and rheumatoid arthritis.

PMID 22224767. In Estonian, Danish, Faroese, Icelandic, Scottish Gaelic and Mandarin Chinese Pinyin, ⟨b⟩ does not denote a voiced consonant. Instead, it represents a voiceless /p/ that contrasts with either a geminated /p:/ (in Estonian) or an aspirated /p h/ (in Danish, Faroese, Icelandic, Scottish Gaelic and Pinyin) represented by ⟨p⟩. In Fijian ⟨b⟩ represents a prenasalised /mb/, whereas in Zulu and Xhosa it represents an implosive /ɓ/, in contrast to the digraph ⟨bh⟩ which represents /b/. Finnish uses ⟨b⟩ only in loanwords.
