Hubs and Webs in Platelet Intracellular Signalling
In this issue of Systems Biology and Physiology Reports A.A. Martyanov and M.A. Panteleev suggested a review on platelet intracellular signalling network, which is a second part in the discussion on the molecular relationships between platelet activation and responses . The review contains seven thousands words and two hundred references and yet it is not complete, as there are still unclear parts in platelet signalling, especially in its inhibition [2-4]. In an effort to comprehend the platelet activation pattern, I drew a signalling scheme based on the review and data from other authors [2, 3].
Overview of the neutralizing antibody and memory B cell response kinetics in SARS-CoV-2 convalescent and/or mRNA vaccinated individuals.
COVID-19 pandemics triggered by the SARS-CoV-2 virus have caused millions of deaths worldwide and have led to expedited developments of various effective vaccines that, if administered, could prevent and/or circumvent the infection and reduce the death toll. Since the start of the pandemics multiple research groups around the world have been involved in the analysis of immune responses of various human cohorts to the SARS-CoV-2 infection and vaccines. Now, over 1.5 years later, the scientific community has accumulated extensive data about both the development of an immune response to SARS-CoV-2 following infection, as well as its rate of fading off. Kinetic analysis of the immune response generated by vaccines is also emerging, enabling the possibility of making comparisons and predictions. In this review we will focus on the comparing B cell and antibody immune responses to the SARS-CoV-2 infection as opposed to mRNA vaccines for the SARS-CoV-2 S-protein, which have been utilized to immunize hundreds of millions of people and analyzed in multiple studies.
