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.

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 ...

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 ...

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.

Pyridoxine, folate, and cobalamin and the condition of the innate and acquired immunity [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2022
The immune response to the pathogen depends on the state and coordinated activity of innate and acquired immunity. To date, the positive role of many micronutrients (vitamins and minerals) in maintaining homeostasis of the human immune system has been ...

Cu,Zn superoxide dismutase genes in Tribolium castaneum: evolution, molecular characterisation and gene expression during immune priming. [PDF]

open access: yes, 2017
The production of reactive oxygen species (ROS) is a normal consequence of the aerobic cell metabolism. Despite their high and potentially detrimental reactivity with various biomolecules, the endogenous production of ROS is a vital part of physiological,
