Low CD4/CD8 Ratio in Bronchus-Associated Lymphoid Tissue Is Associated with Lung Allograft Rejection

Table 4

Summary of recent BALT literature.

Author	Disease state	BALT conclusion
Hogg et al., 2004 [2]	COPD	Increased BALT presence with worsening disease severity
Rangel-Moreno et al., 2006 [3]	Rheumatoid lung	Induced BALT presence correlates with increased lung tissue damage
Prop et al., 1985 [4]	Animal lung transplant	Presence of BALT correlates with rejection. Removal of BALT through irradiation of donor abrogates rejection
Hasegawa et al., 1999 [5]	Human lung transplant	BALT presence correlates with minimal to no rejection. BALT may play role in immune tolerance
