How does spaceflight affect the acquired immune system? [PDF]

open access: yesNPJ Microgravity, 2020
AbstractThe impact of spaceflight on the immune system has been investigated extensively during spaceflight missions and in model experiments conducted on Earth. Data suggest that the spaceflight environment may affect the development of acquired immunity, and immune responses.

Acquired factor XI inhibitor with immune system disorder

open access: hybridMedicine: Case Reports and Study Protocols, 2021
Abstract Rationale: Acquired haemophilia is a bleeding disorder caused by inhibitors developed against endogenous coagulation factors in patients, disrupting the normal haemostasis. Most of the cases with acquired haemophilia present with acquired FVIII inhibitors and FIX inhibitors. Acquired FXI inhibitors in patient

Physical activities, exercises, and their effects to the immune system [PDF]

open access: yesJKKI (Jurnal Kedokteran dan Kesehatan Indonesia), 2016
Every systems in human body correlate to maintain homeostasis. One of those systems which contribute to maintain homeostasis is the immune system. The immune system defends physiological functions against foreign substances and cancer cells through a ...

New Aspect of Immune System: Innate Immunity and Acquired Immunity

open access: bronzeJournal of the Japanese Association for Infectious Diseases, 2006
Recently, it has been turned out that our internal defense system is composed of two distinct components; innate/natural immune system and acquired/adaptive immune system. The former innate immunity is principally located at the surface area such as skin and mucosal compartment, while the latter acquired immunity is observed mainly in the circulating ...

The NKT cell system: bridging innate and acquired immunity [PDF]

open access: bronzeNature Immunology, 2003
Although natural killer T cells are activated during infection, it is not clear how this process occurs. Closer examination indicates that recognition of endogenous ligands and interleukin 12, rather than bacterial products, may drive the activation process.

Cigarette smoke-induced pulmonary emphysema in scid-mice. Is the acquired immune system required? [PDF]

open access: goldRespiratory Research, 2005
Background Chronic obstructive pulmonary disease is associated with a chronic inflammatory response of the host to chronic exposure to inhaled toxic gases and particles. Although inflammatory cells of both the innate and adaptive immune system infiltrate

The adaptive (aka “acquired”) immune system : from friend to foe [PDF]

open access: yesThe Paradox of the Immune System, 2022
The purpose of the immune system is simple—protect the human organism from foreign (antigenic) invasion and resultant disease. The innate immune response (“our best friend”) does a great job of accomplishing that defense under most circumstances. But sometimes, innate immunity confronts an adversary (a pathogen) that overwhelms it and produces a ...

A hierarchical framework of the acquired immune system

open access: green
The acquired immune system provides a general pattern recognition and defence system that modifies itself, adapting to improve its capability with experience. This work elaborates upon and refines the definition of a previously proposed hieratical acquired immune system framework.
