Of Mice and Schoolchildren: A Conceptual History of Herd Immunity.

Authors:
David Robertson

Am J Public Health 2021 Jun 10:e1-e8. Epub 2021 Jun 10.

David Robertson is a doctoral candidate in the Program in the History of Science, Princeton University, Princeton, NJ. He is affiliated with the project "Rethinking Science and Public Participation" (PI: Bruno J. Strasser), University of Geneva, Switzerland.

This article explores a tension at the core of the concept of herd immunity that has been overlooked in public and scientific discussions‒namely: how can immunity, a phenomenon of individual biological defenses, be made relevant to populations? How can collectives be considered "immune"? Over the course of more than a century of use of the term, scientists have developed many different understandings of the concept in response to this inherent tension. Originating among veterinary scientists in the United States in the late 19th century, the concept was adopted by British scientists researching human infectious disease by the early 1920s. It soon became a staple concept for epidemiologists interested in disease ecology, helping to articulate the population dynamics of diseases such as diphtheria and influenza. Read More

Deletion of TLR2 erythro-myeloid progenitors leads to embryonic lethality in mice.

Eur J Immunol 2021 Jun 9. Epub 2021 Jun 9.

Laboratory of Immunobiology, Institute of Molecular Genetics of the Czech Academy of Sciences, Prague, Czech Republic.

Early embryonic hematopoiesis in mammals is defined by three successive waves of hematopoietic progenitors which exhibit a distinct hematopoietic potential and provide continuous support for the development of the embryo and adult organism. Although the functional importance of each of these waves has been analyzed, their spatio-temporal overlap and the lack of wave-specific markers hinders the accurate separation and assessment of their functional roles during early embryogenesis. We have recently shown that TLR2, in combination with c-kit, represents the earliest signature of emerging precursors of the second hematopoietic wave, erythro-myeloid precursors (EMPs). Read More

Sars Cov-2, the pathogen which belongs to the beta coronavirus family that is responsible for COVID-19, uses Angiotensin Converting Enzyme 2 (ACE2) as a receptor, which is responsible for controlling the actions of renin-angiotensin system (RAS). Sars Cov-2 - ACE2 binding leads to a RAS mediated immune response, which targets especially lungs to form ARDS, which in turn, is the most important cause of mortality in COVID-19. CD8 T cell response dominates over CD4 T cell response and natural killer cell dysfunction also leads to CD4 cell dysfunction in COVID-19; this immune dysregulation leads to inappropriate (ARDS) and inadequate (low or quickly waning antibodies) responses to the disease and unfortunately, prepares the patients for re-infections.

Electronic address:

Stem cells support lifelong maintenance of adult organs, but their specific roles during injury are poorly understood. Here we demonstrate that Lgr6 marks a regionally restricted population of epidermal stem cells that interact with nerves and specialize in wound re-epithelialization. Diphtheria toxin-mediated ablation of Lgr6 stem cells delays wound healing, and skin denervation phenocopies this effect. Read More

Department of the Affiliated Eye and ENT Hospital, State Key Laboratory of Medical Neurobiology, ENT Institute and Otorhinolaryngology, Fudan University, Room 613, Building 9, No. 83, Fenyang Road, Shanghai 200031, China; Institutes of Biomedical Sciences, Fudan University, Shanghai 200032, China; NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China; Shanghai Engineering Research Centre of Cochlear Implant, Shanghai 200031, China; The Institutes of Brain Science and the Collaborative Innovation Center for Brain Science, Fudan University, Shanghai 200032, China. Electronic address:

Loss of hair cells (HCs) accounts for most sensorineural hearing loss, and regeneration of cochlear HCs is considered as the ultimate strategy for restoring hearing. Several lines of evidence have shown that Lgr5+ progenitor cells can spontaneously regenerate new HCs after HC loss at the neonatal stage, and most of which are immature. IHCs are resistant to ototoxic drugs and noise and cannot be ablated efficiently in order to precisely investigate IHC regeneration in existing hearing injury models, and thus we generated a new transgenic mouse model by inserting diphtheria toxin receptor (DTR) under the control of the Vglut3 promoter.
