Building a strong immune system that could defeat COVID-19
You may not know it, but you have an army of microbes living inside of you that are essential for fighting off threats, including the virus that causes COVID-19. In the past two decades scientists have learned our bodies are … Continue reading

The immune system and its ecology
In biology, the ‘ecological orientation’ rests on a commitment to examining systems, and the conceptual challenge of defining that system now employs techniques and concepts adapted from diverse disciplines (i.e., systems philosophy, cybernetics, information theory, computer science) that are applied … Continue reading
The Inclusive Behavioral Immune System
Although living in social groups offers many advantages, it comes at a cost of increased transmissible disease. The behavioral immune system (BIS) is thought to have evolved as a first line of defense against such infections. It acts by minimizing the contact … Continue reading
Viral evolution under the pressure of an adaptive immune system
Based on a recent model of evolving viruses competing with an adapting immune system (Kamp and Bornholdt, Co-evolution of quasispecies: B-cell mutation rates maximize viral error catastrophes. Phys Rev Lett 88, 2002), we study the conditions under which a viral quasispecies can … Continue reading

Brain and the immune system: Multiple sites of interaction
Converging data from different disciplines indicate that central nervous system processes are capable of influencing immune responses. This paper concentrates on ecent studies documenting behaviorally conditioned suppression and enhancement of immunity. Exposing rats or mice to a conditioned stimulus previously paired with … Continue reading

The immune system as a biomonitor: explorations in innate and adaptive immunity
The human immune system has a highly complex, multi-layered structure which has evolved to detect and respond to changes in the internal microenvironment of the body. Recognition occurs at the molecular or submolecular scale, via classical reversible receptor-ligand interactions, and … Continue reading

Evolution of the immune system in humans from infancy to old age
This article reviews the development of the immune response through neonatal, infant and adult life, including pregnancy, ending with the decline in old age. A picture emerges of a child born with an immature, innate and adaptive immune system, which … Continue reading

Low Social Status May Weaken Immune System in Monkeys
Life at the bottom of the pecking order ramps up inflammation, according to new research, an effect that appears to be reversible. The link between social class and health in social mammals has been well documented. But new research in rhesus … Continue reading

Immune System Maintains Brain Health
Once thought only to attack neurons, immune cells turn out to be vital for central nervous system function. Kipnis’s work is part of a wave of research changing the way scientists view the relationship between the immune system and the … Continue reading
