Impacts of COVID on the immune system


Authors: Lara Herrero, The Conversation Medical Xpress September 19, 2022 So you’ve had COVID and have now recovered. You don’t have ongoing symptoms and luckily, you don’t seem to have developed long COVID. But what impacts has COVID had on your overall immune system? It’s early days yet. But growing evidence suggests there are changes to […]

TAuthors: oral Shastri 1, Navkiran Randhawa 2, Ragia Aly 3, Masood Ghouse 3 PMID: 35210894PMCID: PMC8863340DOI: 10.2147/JBM.S350290 J Blood Med.  2022; 13: 69–74.Published online 2022 Feb 18. doi: 10.2147/JBM.S350290 Abstract As of September 2021, SARS-CoV-2 booster shots became widely available in the US to ensure continued protection against the virus. A temporal relationship has been previously reported between the first or second dose of the COVID-19 vaccine […]

Bone Marrow Suppression Secondary to the COVID-19 Booster Vaccine: A Case Report


Authors: Toral Shastri 1, Navkiran Randhawa 2, Ragia Aly 3, Masood Ghouse 3 PMID: 35210894 PMCID: PMC8863340DOI: 10.2147/JBM.S350290 Abstract As of September 2021, SARS-CoV-2 booster shots became widely available in the US to ensure continued protection against the virus. A temporal relationship has been previously reported between the first or second dose of the COVID-19 vaccine and the development of thrombocytopenia. However, adverse events related […]

SARS-CoV-2 infection induces long-lived bone marrow plasma cells in humans


Authors: Jackson S. Turner, Wooseob Kim, Elizaveta Kalaidina, Charles W. Goss, Adriana M. Rauseo, Aaron J. Schmitz, Lena Hansen, Alem Haile, Michael K. Klebert, Iskra Pusic, Jane A. O’Halloran, Rachel M. Presti & Ali H. Ellebedy  Nature volume 595, pages421–425 (2021) Abstract Long-lived bone marrow plasma cells (BMPCs) are a persistent and essential source of protective antibodies1,2,3,4,5,6,7. Individuals who have recovered from COVID-19 have a substantially lower risk of reinfection with […]

Pre-existing immunity to SARS-CoV-2: the knowns and unknowns


Authors: Alessandro Sette 1 2, Shane Crotty 3 4 Abstract T cell reactivity against SARS-CoV-2 was observed in unexposed people; however, the source and clinical relevance of the reactivity remains unknown. It is speculated that this reflects T cell memory to circulating ‘common cold’ coronaviruses. It will be important to define specificities of these T cells and assess their association […]

A long-term perspective on immunity to COVID


Determining the duration of protective immunity to infection by SARS-CoV-2 is crucial for understanding and predicting the course of the COVID-19 pandemic. Clinical studies now indicate that immunity will be long-lasting. Authors: Andreas Radbruch & Hyun-Dong Chang Generating immunity against the SARS-CoV-2 coronavirus is of the utmost importance for bringing the COVID-19 pandemic under control, protecting vulnerable […]

COVID-19 survivors may possess wide-ranging resistance to the disease


Authors: Rajee Suri rajee.suri@emory.edu Recovered COVID-19 patients retain broad and effective longer-term immunity to the disease, suggests a recent Emory University study, which is the most comprehensive of its kind so far. The findings have implications for expanding understanding about human immune memory as well as future vaccine development for coronaviruses. The longitudinal study, published […]

Adaptive immune responses to SARS-CoV-2 infection in severe versus mild individuals


Authors: Fan Zhang, Rui Gan, Ziqi Zhen, Xiaoli Hu, Xiang Li, Fengxia Zhou, Ying Liu, Chuangeng Chen, Shuangyu Xie, Bailing Zhang, Xiaoke Wu & Zhiwei Huang Signal Transduction and Targeted Therapy volume 5, Article number: 156 (2020)  Abstract The global Coronavirus disease 2019 (COVID-19) pandemic caused by SARS-CoV-2 has affected more than eight million people. There is an urgent need to investigate how the adaptive immunity is established in COVID-19 patients. In this […]

Adaptive immunity to SARS-CoV-2 and COVID-19


Authors: Alessandro Sette1,2 and Shane Crotty1,2,∗ Abstract The adaptive immune system is important for control of most viral infections. The three fundamental components of the adaptive immune system are B cells (the source of antibodies), CD4+ T cells, and CD8+ T cells. The armamentarium of B cells, CD4+ T cells, and CD8+ T cells has differing roles in different viral infections and in vaccines, and […]
