求翻译：Bronchus-associated lymphoid tissue (BALT) was originally described as a mucosal lymphoid organ in the lungs of some species. However, while the lungs of naive mice and humans typically lack BALT, pulmonary infection in mice leads to the development of inducible BALT (iBALT), which is located in peribronchial, perivascular, and interstitial areas throughout the lung. Here we investigated whether iBALT forms in patients with a variety of interstitial lung diseases. We show that while iBALT can be found in the lungs of patients suffering from multiple diseases, well-developed iBALT is most prevalent in patients with pulmonary complications of RA and Sj是什么意思？
