A series of adaptive models inspired by the acquired immune system

open access: green
The acquired immune system is capable of specialising a defence of an organism in response to the its antigenic environment. This complex biological system possess interesting information processing features such as learning, memory, and the ability to generalize.

Role of NPR1 in Systemic Acquired Stomatal Immunity

open access: yesPlants, 2023
Stomatal immunity is the primary gate of the plant pathogen defense system. Non-expressor of Pathogenesis Related 1 (NPR1) is the salicylic acid (SA) receptor, which is critical for stomatal defense. SA induces stomatal closure, but the specific role of NPR1 in guard cells and its contribution to systemic acquired resistance (SAR) remain largely ...

The role of the acquired immune response in systemic sclerosis [PDF]

open access: yesSeminars in Immunopathology, 2015
Profound alterations characterize the adaptive immune response in systemic sclerosis, and several layers of evidence support a prominent role exerted by immune cellular effectors and humoral mediators in the pathogenesis of this disease. These include (i) the presence of oligoclonal T cells in tissues undergoing fibrosis consistent with (auto)antigen ...

Paleo-immunology: evidence consistent with insertion of a primordial herpes virus-like element in the origins of acquired immunity. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:The RAG encoded proteins, RAG-1 and RAG-2 regulate site-specific recombination events in somatic immune B- and T-lymphocytes to generate the acquired immune repertoire.

A Spatial Transcriptome Reveals Changes in Tumor and Tumor Microenvironment in Oral Cancer with Acquired Resistance to Immunotherapy

open access: yesBiomolecules, 2023
Although anti-programmed death-1 (PD-1) antibody therapy improves the prognosis in patients with head and neck squamous cell carcinoma (HNSCC), some patients exhibit disease progression even after showing a good response to the treatment initially ...

Effect of Nicotine on Immune System Function [PDF]

open access: yesAdvanced Pharmaceutical Bulletin, 2023
As a parasympathetic alkaloid and the main substance in cigarette smoke, nicotine modulates the immune system, inhibits innate and acquired immunity and is used in treating many autoimmune diseases.

Exploring the Effect of Probiotics, Prebiotics, and Postbiotics in Strengthening Immune Activity in the Elderly

open access: yesVaccines, 2021
Vaccination is the easiest way to stimulate the immune system to confer protection from disease. However, the inefficacy of vaccination in the elderly, especially those under nutritional control such as individuals receiving artificial nutrition after ...

Infections with extracellular trypanosomes require control by efficient innate immune mechanisms and can result in the destruction of the mammalian humoral immune system [PDF]

open access: yes, 2020
Salivarian trypanosomes are extracellular parasites that affect humans, livestock, and game animals around the world. Through co-evolution with the mammalian immune system, trypanosomes have developed defense mechanisms that allow them to thrive in blood,

Evolutionary trade-off between innate and acquired immune defences in birds

open access: yesFrontiers in Zoology, 2023
Background The development, maintenance, and use of immune defences are costly. Therefore, animals face trade-offs in terms of resource allocation within their immune system and between their immune system and other physiological processes.

Intracellular infection and immune system cues rewire adipocytes to acquire immune function

open access: yesCell Metabolism, 2022
Adipose tissue (AT) plays a central role in systemic metabolic homeostasis, but its function during bacterial infection remains unclear. Following subcutaneous bacterial infection, adipocytes surrounding draining lymph nodes initiated a transcriptional response indicative of stimulation with IFN-γ and a shift away from lipid metabolism toward an ...
