Biophysical investigation on therapeutic proteins (Chaperonins, Hsp60 and CCT/TRiC) involved in human diseases

Molecular chaperones are indispensable cellular components that assist folding and assembly of newly synthesized proteins, translocation of proteins across membranes, as well as refolding and degrading of misfolded and aggregated proteins. In the last few years, innovative therapeutic strategies targeting stability and functionality of chaperones have received great attention, particularly in the field of neurodegenerative diseases. Moreover, the growing number of diseases found linked to chaperone mutations, testifies to the importance of their role in the cellular protein-quality control mechanism. The investigation of the biophysical interactions between chaperones and specific proteins …

Macrophage inflammatory protein-1.

2003

Macrophage inflammatory protein (MIP)-1alpha was identified 15 years ago as the first of now four members of the MIP-1 CC chemokine subfamily. These proteins termed CCL3 (MIP-1alpha), CCL4 (MIP-1beta), CCL9/10 (MIP-1delta), and CCL15 (MIP-1gamma) according to the revised nomenclature for chemokines are produced by many cells, particularly macrophages, dendritic cells, and lymphocytes. MIP-1 proteins, which act via G-protein-coupled cell surface receptors (CCR1, 3, 5), e.g. expressed by lymphocytes and monocytes/macrophages (MPhi), are best known for their chemotactic and proinflammatory effects but can also promote homoeostasis. The encouraging results of preclinical studies in murine model…

Grafiskā dizaina un tehnoloģiskie risinājumi koka kalendāra izveidē

2017

Diplomdarbā “Grafiskā dizaina un tehnoloģiskie risinājumi koka kalendāra izveidē” autors pēta kalendāru vēsturi, kalendāru veidus un to ražošanas tehnoloģiskās iespējas. Darbā pēc četriem kritērijiem tika analizēti vairāki dažādu pasaules un Latvijas kalendāru dizainu paraugi. Cilvēki nevar iztikt bez laika plānošanas sistēmas, to lieto ikviens, bet kalendāra veidu un dizainu katrs izvēlas atbilstoši gaumei un dzīves stilam. Darba mērķis ir izveidot radošu galda kalendāra dizainu no koka plāksnēm, izmantojot lāzergravēšanas tehniku. Radošajā daļā tika izveidots unikāls 12 mēnešu kalendārs ar koka statīvu. Kalendāra izveidē vienlīdz liela uzmanība tika veltīta abām kalendāra funkcijām- infor…

The STATe of the Neuron Leads to Synaptic Stripping

2018

In a recent issue of Cell, Di Liberto et al. (2018) elucidate the mechanisms involved in synaptic stripping during viral infection. Infected neurons orchestrate their own synaptic loss downstream of IFNγ signaling, ultimately attracting phagocytic monocytes into the CNS through CCL2 production.

Clinical correlates of change in inflammatory biomarkers: The Framingham Heart Study

2013

Objectives: Traditional clinical risk factors are associated with inflammation cross-sectionally, but associations of longitudinal variation in inflammatory biomarkers with corresponding changes in clinical risk factors are incompletely described. We sought to analyze clinical factors associated with change in inflammation in the community.Methods: We studied 3013 Framingham Offspring (n = 2735) and Omni Cohort (n = 278) participants (mean age 59 years, 55% women, 9% ethnic/racial minority) who attended two consecutive examination cycles (mean 6.7 years apart). We selected ten inflammatory biomarkers representing distinctive biological functions: C-reactive protein (CRP), intercellular adhe…

Prognostic value of immunoexpression of CCR4, CCR5, CCR7 and CXCR4 in squamous cell carcinoma of tongue and floor of the mouth.

2018

Background Diverse studies have evidenced that chemokines can play a critical role in pathogenesis of oral squamous cell carcinoma (SCC). The main chemokines involved in oral carcinogenesis, tumor invasion and metastasis are CCR4, CCR5, CCR7 and CXCR4, and our aim was to evaluate the prognostic value of the immunoexpression of these chemokines in SCC of tongue and floor of the mouth. Material and Methods A retrospective descriptive study of the immunohistochemical expression of CCR4, CCR5, CCR7 and CXCR4 in paraffin-embedded samples of 124 patients with SCC of the tongue and floor of the mouth was performed, considering 98 cases from Brazil and 26 cases from Chile. Associations between vari…

Traditional Chinese herbal medicine at the forefront battle against COVID-19: Clinical experience and scientific basis.

2020

Abstract Background Throughout the 5000-year history of China, more than 300 epidemics were recorded. Traditional Chinese herbal medicine (TCM) has been used effectively to combat each of these epidemics’ infections, and saved many lives. To date, there are hundreds of herbal TCM formulae developed for the purpose of prevention and treatment during epidemic infections. When COVID-19 ravaged the Wuhan district in China in early January 2020, without a deep understanding about the nature of COVID-19, patients admitted to the TCM Hospital in Wuhan were immediately treated with TCM and reported later with >90% efficacy. Approach We conducted conduct a systematic survey of various TCM herbal pre…

Subendothelial infiltration of neutrophil granulocytes and liberation of matrix-destabilizing enzymes in an experimental model of human neo-intima.

2008

SummaryIt was the objective of this study to examine the role of human neutrophil granulocytes (PMN) in an in-vitro model of human neo-intima developed for the study of atherosclerosis. Human granulocytes were subjected to a co-culture model of human endothelial and smooth muscle cells. Subendothelial lipid accumulation was achieved by addition of native LDL to the culture medium. Tissue samples were analyzed by immunohistochemistry and scanning/transmission electron microscopy, and culture supernatants were examined for the presence of interleukin- 8 (IL-8), MCP-1, GRO-α, elastase and matrixmetalloproteinase-8 (MMP-8). Following addition of 2 mg/ml LDL, adherence, transmigration and infilt…

Spatial and temporal heterogeneity of ventilator-associated lung injury after surfactant depletion.

2008

Volutrauma and atelectrauma have been proposed as mechanisms of ventilator-associated lung injury, but few studies have compared their relative importance in mediating lung injury. The objective of our study was to compare the injury produced by stretch (volutrauma) vs. cyclical recruitment (atelectrauma) after surfactant depletion. In saline-lavaged rabbits, we used high tidal volume, low respiratory rate, and low positive end-expiratory pressure to produce stretch injury in nondependent lung regions and cyclical recruitment in dependent lung regions. Tidal changes in shunt fraction were assessed by measuring arterial Po2 oscillations. After ventilating for times ranging from 0 to 6 h, lu…
