In LN patients, ESR correlated positively with the frequencies of PD-1+CD3+ T cells (r = 0.388, p < 0.01), PD-1+CD4+ T cells (r = 0.273, p < 0.05), and PD-1+CD8+ T cells (r = 0.273, p < 0.05), whereas these associations were absent in LN-negative cases. This evidence concerns the gene CD8A and lobular neoplasia.
