Background: Streptococcus suis is an important swine pathogen and zoonotic agent. Infection with this highly pathogenic strain can cause streptococcal toxic shock-like syndrome (STSLS), characterized by a Th-1 inflammatory cytokine storm, and a high mortality rate. Monocyte derived dendritic cells (MoDCs) are known to stimulate Th-1 cell differentiation, but the role of MoDCs in STSLS remains to be elucidated.

Methodology/principal Findings: To explore the effects of mtDNA haplogroups on the prevalence of extreme longevity (EL), a population based case-control study was conducted in Rugao--a prefecture city in Jiangsu, China. Case subjects include 463 individuals aged > or = 95 yr (EL group).
Article Synopsis
- The Han Chinese, the largest ethnic group globally, consists of various branches, among which the Pinghua branch has been less studied but is believed to derive from ancient southern minorities.
- Genetic analyses of 470 samples show that Pinghua populations display high frequencies of certain Y chromosome haplogroups and mtDNA lineages similar to those found in nearby indigenous groups, indicating a closer relationship with southern minorities than with other Han branches.
- Overall, the findings suggest that while the Pinghua have adopted Han Chinese culture and language, their genetic roots trace back to southern minorities rather than the broader Han Chinese lineage.
