New Evidence of Ancient Mitochondrial DNA of the Southern Andes (Calchaquí Valleys, Northwest Argentina, 3,600-1,900 Years before Present)
Genetic studies in the pre-Hispanic population of Southern Andes have risen steadily in the last decade. However, the characterization of ancient DNA Formative Period archaeological remains of humans is lacking, especially for Northwest Argentina.
To expand the current information on the genetic characterization of the first farming communities of southern Calchaquí Valleys, we present and discuss the first ancient mitochondrial DNA information obtained on the sample dates to ca. 3.600 to 1.900 years before present from Cajon Valley, Catamarca Province. Reproduced mtDNA hypervariable region 1 (HVR-1) was obtained in seven individual sequences. Mitochondria HVR-1 haplotype assigned to three of the four founding haplogroups, D1 (57.1%), C1 (28.5%), and B2 (14.2%), in the absence of A2.
Our results indicate that the Cajon Valley of the sample, with a predominance of D1 and C1, is different from that commonly seen in ancient and modern Andean populations, which usually indicates a high prevalence of haplogroup B2. The fact that Cajon Valley and Pampa Grande (Salta Province, Argentina) shared the prevalence of haplogroup D1 can provide additional evidence to support the genetic affinity may be between the valleys and the sub-Andean region of the east during the Period Formative in Northwest Argentina, expand the archaeological evidence of contacts between the two population. Future full mitogenomic analysis will provide important information to formulate new hypotheses on the origin and phylogenetic relationships between individuals from Cajon Valley and other groups of the Andes, the Gran Chaco, and the Amazon.
Although recent studies suggest the involvement of monocytes to accelerate lesion formation neuromyelitis optica spectrum disorders (NMOSD), the exact mechanism of activation of the innate immune system remains elusive. Thus, in this study, we aimed to clarify the mechanism of pathogenesis NMOSD from the standpoint of innate immune activation. We established a recombinant anti-AQP4 autoantibodies (Ab) of plasmablasts in CSF NMOSD patients. Human astrocytes were treated with anti-AQP4 Ab produce large amounts of CCL2 and contributing to the efficient recruitment of monocytes.

Disadvantages relationship between mitochondrial DNA haplogroup J and T and clinical manifestations in patients with Brugada syndrome Russia
Brugada Syndrome (BRS) is a congenital disorder characterized by specific ST segment elevation in the right precordial leads, pseudo right bundle branch block, and a high risk of sudden cardiac death due to ventricular tachycardia. Was originally described as a monogenic disorder with an autosomal dominant mode of inheritance.
It is hypothesized that modifying the genetic factors, in addition to disease-causing mutations, can significantly contribute to the clinical symptoms and the risk of sudden cardiac death. Modifying factors may include mitochondrial DNA (mtDNA) variants. In particular, the combination of mtDNA m.T4216C, m.A11251G, m.C15452A and variants m.T16126C (defining haplogroup T and J), considered to be a factor that promotes the manifestation of BRS manifestations, without pro-arrhythmic effect.

The purpose of this study is to confirm the association reported to BRS with mtDNA variants in the group of patients Russia. mtDNA haplogroup genotyped in 47 probands BRS Russia and the prevalence of mtDNA haplogroups common than the general population in the European part of Russia. Distribution and prevalence of all but the mtDNA haplogroup J BRS comparable in probands and general Russian population. Mitochondrial haplogroup J was not found in the BRS cohort. In conclusion, it was shown that mtDNA polymorphisms, m.T4216C (haplogroup J and T) does not contribute significantly to the clinical manifestations in patients BRS Russia.
