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

Sick Body, Vigilant Mind: The Biological Immune System Activates the Behavioral Immune System

Activation of the behavioral immune system has been shown to promote activation of the biological immune system. The current research tested the hypothesis that activation of the biological immune system (as a result of recent illness) promotes activation of the … 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

The immune system’s fight against the coronavirus

How does our immune system react to the coronavirus? A central player in the fight against the novel coronavirus is our immune system. It protects us against the invader and can even be helpful for its therapy. But sometimes it … Continue reading

Immune system

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to … Continue reading
