Objective: To assess the association of RNASET2 gene polymorphisms and haplotypes with Graves disease (GD) in Han Chinese population from coastal regions of Shandong Province.
Methods: A total of 471 GD patients and 472 controls were enrolled. Genotypes of single nucleotide polymorphisms (SNPs) in RNASET2 gene were determined with a Taqman probe on a Fluidigm EPl platform. Haplotypes and their frequencies were analyzed with a SHEsis online software.
Results: There was a significant difference in allele frequencies of rs3777722, rs3777723 and rs9355610 between the GD patients and the controls (P=0.018; P=0.028; P=0.021).Allele frequencies of rs3777722 and rs9355610 were significantly lower in GD than in the controls (P=0.018, P=0.021). Haplotypes A-A-C-A and A-A-T-A were significantly more common in the control group compared with the GD group (P=0.046, OR=0.448, 95%CI:0.200-1.006; P=0.049, OR=0.823, 95%CI:0.678-0.999). The frequency of C-G-C-G haplotype was significantly higher in GD patient group than the control group (P=0.018).
Conclusion: RNASET2 gene polymorphisms and haplotypes are associated with GD in Han population from coastal areas of Shandong Province. rs3777722 and rs9355610 may contribute to the risk for GD.

RNase T2 deficiency promotes TLR13-dependent replenishment of tissue-protective Kupffer cells.

Lysosomal stress due to the accumulation of nucleic acids (NAs) activates endosomal TLRs in macrophages. Here, we show that lysosomal RNA stress, caused by the lack of RNase T2, induces macrophage accumulation in multiple organs such as the spleen and liver through TLR13 activation by microbiota-derived ribosomal RNAs. TLR13 triggered emergency myelopoiesis, increasing the number of myeloid progenitors in the bone marrow and spleen.

RNA-sensing TLRs are strategically positioned in the endolysosome to detect incoming nonself RNA. RNase T2 plays a critical role in processing long, structured RNA into short oligoribonucleotides that engage TLR7 or TLR8. In addition to its positive regulatory role, RNase T2 also restricts RNA recognition through unknown mechanisms, as patients deficient in RNase T2 suffer from neuroinflammation.

Article Synopsis
- The study examines the genetic connection between autoimmune thyroid disease (AITD) and oral lichen planus (OLP), which may reveal how these conditions are related.
- A two-step Mendelian randomization analysis identified that AITD may increase the risk of developing OLP, possibly influenced by hypothyroidism and shared genetic factors, particularly the PTPN22 gene.
- The research emphasizes the importance of understanding endocrine changes in oral health, suggesting a need for further investigation to confirm these findings.

Article Synopsis
- * RNASET2 is associated with NET formation upon activation of neutrophils by various stimuli, and it is found in both mature neutrophils and macrophages in inflamed tissues.
- * Research indicates that RNASET2 levels in circulation correlate with the severity of autoimmune diseases like rheumatoid arthritis, suggesting it may be influential in the disease's development and progression.
