COMPARATIVE ANALYSIS OF FRESHWATER PHYTOPLANKTON COMMUNITIES IN TWO LAKES OF BURABAY NATIONAL PARK USING MORPHOLOGICAL AND MOLECULAR APPROACHES

Malashenkov, Dmitry V.; Dashkova, Veronika; Zhakupova, Kymbat; Vorobjev, Ivan A.; Barteneva, Natasha S. (Scientific Reports, 2021-08-09)

We analyzed phytoplankton assemblages’ variations in oligo-mesotrophic Shchuchie and Burabay lakes using traditional morphological and next-generation sequencing (NGS) approaches. The total phytoplankton biodiversity and ...
Cyclic AMP pathway suppress autoimmune neuroinflammation by inhibiting functions of encephalitogenic CD4 T cells and enhancing M2 macrophage polarization at the site of inflammation

Barteneva, Natasha S. (Nazarbayev University School of Sciences and Humanities, 2018-01-28)

Although it has been demonstrated that cAMP pathway affect both adaptive and innate cell functions, the role of this pathway in the regulation of T-cell-mediated central nervous system (CNS) autoimmune inflammation, such ...
Diagnostic Potential of Imaging Flow Cytometry

Vorobyev, Ivan; Barteneva, Natasha S. (Nazarbayev University School of Sciences and Humanities, 2018-07-01)

Imaging flow cytometry (IFC) captures multichannel images of hundreds of thousands of single cells within minutes. IFC is seeing a paradigm shift from low- to high-information-content analysis, driven partly by deep learning ...
Extracellular vesicles in gastrointestinal cancer in conjunction with microbiota: On the border of Kingdoms

Barteneva, Natasha S.; Baiken, Yeldar; Sautbayeva, Zarina; Kauanova, Sholpan (Nazarbayev University School of Sciences and Humanities, 2017-12-01)

Extracellular vesicle (EV) production is a universal feature of metazoan cells as well as prokaryotes (bMVs - bacterial microvesicles). They are small vesicles with phospholipid membrane carrying proteins, DNA and different ...
Myeloid cells in intact human cervical explants capture HIV and can transmit it to CD4 T cells

Barteneva, Natasha S. (Nazarbayev University School of Sciences and Humanities, 2018-11-28)

The importance of myeloid cells in HIV transmission in the female genital tract is uncertain. Because it is difficult to study the early events in HIV transmission in humans, most of our knowledge is based on animal models ...
Neuronal extracellular microRNAs miR-124 and miR-9 mediate cell-cell communication between neurons and microglia

Veremeyko, Tatyana; Kuznetsova, Inna; Dukhinova, Marina; Yung, Amanda; Kopeikina, Ekaterina; Barteneva, Natasha S.; Ponomarev, Eugene D. (National Laboratory Astana, 2019-10-27)

In contrast to peripheral macrophages, microglia in the central nervous system (CNS) exhibit a specific deactivated phenotype; however, it is not clear how this phenotype is maintained. Two alternative hypotheses were ...
SEMI‑AUTOMATED CLASSIFCATION OF COLONIAL MICROCYSTIS BY FLOWCAM IMAGING FOW CYTOMETRY IN MESOCOSM EXPERIMENT REVEALS HIGH HETEROGENEITY DURING SEASONAL BLOOM

Mirasbekov, Yersultan; Zhumakhanova, Adina; Zhantuyakova, Almira; Sarkytbayev, Kuanysh; Malashenkov, Dmitry V.; Baishulakova, Assel; Dashkova, Veronika; Davidson, Thomas A.; Vorobjev, Ivan A.; Jeppesen, Erik; Barteneva, Natasha S. (Nature Research, 2021-04-30)

A machine learning approach was employed to detect and quantify Microcystis colonial morphospecies using FlowCAM-based imaging flow cytometry. The system was trained and tested using samples from a long-term mesocosm ...
