Increased B cell activating factor is associated with B cell class switching in patients with tuberculous pleural effusion.

B cell activating factor (BAFF), a member of the tumor necrosis factor family, is a key cytokine for B cell survival, a function that is essential for B cell maturation and memory. The expression levels of BAFF and its potential contribution to B cell maturation remain elusive in patients with tuberculous pleural effusion (TPE). The present study enrolled 40 healthy controls (HC) and 45 TPE patients, and investigated the levels of BAFF in the plasma and pleural effusion.

Profiling dendritic cell subsets in the patients with active pulmonary tuberculosis.

Dendritic cell (DC) plays an important role in the immune response against pulmonary tuberculosis. However, the phenotypic profile of DC subsets in peripheral blood in individuals with active pulmonary tuberculosis (APT) is still inconclusive. Here, we demonstrated that the absolute numbers of total DC (tDC), myeloid DC (mDC) and plasmacytoid DC (pDC) in individuals with APT were decreased compared to healthy controls (HCs).

The circular RNA of peripheral blood mononuclear cells: Hsa_circ_0005836 as a new diagnostic biomarker and therapeutic target of active pulmonary tuberculosis.

It has been reported that circular RNA (circRNA) is associated with human cancer. However, few studies have been reported in active pulmonary tuberculosis (APTB). The global circRNA expression was detected in the peripheral blood mononuclear cells (PBMCs) of APTB patients (n=5) and health controls (HC) (n=5) by using high-throughput sequencing.

Development and characterization of monoclonal antibody against human IL-37b.

IL-37 has been described as a natural inhibitor of immune responses. Monoclonal antibody (mAb) against human IL-37b with high affinity and specificity can serve as a molecular probe to detect IL-37 and study IL-37 functions, mechanisms and related signal pathways in inflammatory diseases. However, there are very few such mAbs against human IL-37 commercially available so far.
