The investigation of the dynamics and regulation of virus-triggered innate immune signaling pathways at a system level will enable comprehensive analysis of the complex interactions that maintain the delicate balance between resistance to infection and viral disease. In this study, we developed a delayed mathematical model to describe the virus-induced interferon (IFN) signaling process by cons...

the cd30 antigen seems to play a costimulatory role in maintaining the physiological balance between t-helper (th)1/th2 immune responses. in this study, plasma and in vitro soluble cd30 (scd30) secretion was investigated in patients with coronary artery disease (cad) as a plausible marker of dysregulated immune response. twenty one patients with angiographically confirmed cad and 31 healthy con...

In a large proportion of individuals nervous system damage may lead to a debilitating chronic neuropathic pain. Such pain may now be considered a neuro-immune disorder, since recent data indicate a critical involvement of innate and adaptive immune responses following nerve injury. Activation of immune and immune-like glial cells in the injured nerve, dorsal root ganglia and spinal cord results...

Plants assemble beneficial root-associated microbiomes to support growth, especially in nutrient-poor conditions. To do so, however, plants have to suppress their immune system. Reporting in Nature, Castrillo et al. (2017) identified PHOSPHATE STARVATION RESPONSE1 (PHR1) as a central regulator in this balance between nutrient stress response and immune regulation.

Research on microbe-host interactions focuses principally on pathogens, yet our immune system must deal with the huge number of beneficial commensal bacteria in our gut. It is becoming clear that the host immune system must reach a delicate balance between destroying dangerous bacterial pathogens while preserving the beneficial gut microbiota.

SLC11A1 is known to link infections, autoimmunity and cancers. A review is presented of the mechanisms by which a balance is maintained between infections caused by pathogens (viral, bacterial and protozoan; intracellular and extracellular) and disorders resulting from (acute or chronic) inflammation, and of the interactions that determine how the initial innate immune system directs subsequent...

Competition within the immune system may degrade immune control of viral infections. We formalize the evolution that occurs in both HIV-1 and the immune system quasispecies. Inclusion of competition in the immune system leads to a novel balance between the immune response and HIV-1, in which the eventual outcome is HIV-1 escape rather than control. The analytical model reproduces the three stag...

Effective immune responses are coordinated by interactions among the nervous, endocrine, and immune systems. Mounting immune, inflammatory, and sickness responses requires substantial energetic investments, and as such, an organism may need to balance energy allocation to these processes with the energetic demands of other competing physiological systems. The metabolic hormone leptin appears to...

Numerous analyses of large patient cohorts identified specific patterns of immune activation associated with patient survival. We established these as the immune contexture, encompassing the type, functional orientation, density, and location of adaptive immune cells within distinct tumor regions. Based on the immune contexture, a standardized, powerful immune stratification system, the Immunos...

BACKGROUND AND OBJECTIVES The human immune system is an ever-changing composition of innumerable cells and proteins, continually ready to respond to pathogens or insults. The cost of maintaining this state of immunological readiness is rarely considered. In this paper we aim to discern a cost to non-acute immune function by investigating how low levels of C-reactive protein (CRP) relate to othe...
