THE BIOTIC FACTOR OF TREMATOD OPISTHORHIS FELINEUS INVASION INFLUENCE ON HOST IMMUNE STATUS AND SOMATIC CELLS PROLIFERATIVE ACTIVITY

open access: yesИнфекция и иммунитет, 2016
The paper confirms long-time opisthorhis invasion role as a risk factor of host immune system reconstitution as well as an important factor in holangiocarcinomas development. It was shown that opisthorhosis invasion primal stage induce host immune system

SPECIFIC CARCINOEMBRYONIC ANTIGENS OF THE HUMAN DIGESTIVE SYSTEM

open access: yesJournal of Experimental Medicine, 1965
A wide variety of human adult and fetal tissues were studied by immune-diffusion techniques in agar gel to determine whether they contained the tumor-specific antigen(s) previously found in coionic cancers.

The Humoral Theory of Transplantation: Epitope Analysis and the Pathogenicity of HLA Antibodies. [PDF]

open access: yes, 2016
Central to the humoral theory of transplantation is production of antibodies by the recipient against mismatched HLA antigens in the donor organ. Not all mismatches result in antibody production, however, and not all antibodies are pathogenic.

Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation

open access: yesFEBS Letters, EarlyView.
Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

Integrating influenza antigenic dynamics with molecular evolution [PDF]

open access: yesarXiv, 2013
Influenza viruses undergo continual antigenic evolution allowing mutant viruses to evade host immunity acquired to previous virus strains. Antigenic phenotype is often assessed through pairwise measurement of cross-reactivity between influenza strains using the hemagglutination inhibition (HI) assay.

A stochastic individual-based model to explore the role of spatial interactions and antigen recognition in the immune response against solid tumours [PDF]

open access: yes, 2019
Spatial interactions between cancer and immune cells, as well as the recognition of tumour antigens by cells of the immune system, play a key role in the immune response against solid tumours. The existing mathematical models generally focus only on one of these key aspects.

Expansion of host range as a driving force in the evolution of Toxoplasma

open access: yesMemorias do Instituto Oswaldo Cruz, 2009
The apicomplexan parasite Toxoplasma gondii is unusual in being able to infect almost any cell from almost any warm-blooded animal it encounters. This extraordinary host-range contrasts with its far more particular cousins such as the various species of ...

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Duration of humoral immunity to common viral and vaccine antigens.

open access: yesNew England Journal of Medicine, 2007
BACKGROUND Maintenance of long-term antibody responses is critical for protective immunity against many pathogens. However, the duration of humoral immunity and the role played by memory B cells remain poorly defined.
