This study demonstrates just how vital the thymus is to maintaining adult health." « Back to Top Does Amyloid-β Aggregation Cause Broad Disruption of Proteostasis? https://www.fightaging.org/archives/2023/08/does-amyloid-%ce%b2-aggregation-cause-broad-disruption-of-proteostasis/ Researchers here speculate on the ability of insoluble amyloid-β aggregates to be broadly disruptive of the solubility of many other proteins, and thus disruptive to cell and tissue function. Is this important in aging? The evidence here shows the existence of the mechanism in a lower species, but that doesn't n...

Biomaterial-based delivery platforms for transdermal immunotherapy
Biomed Pharmacother. 2023 Jun 27;165:115048. doi: 10.1016/j.biopha.2023.115048. Online ahead of print.ABSTRACTNowadays, immunotherapy is one of the most essential treatments for various diseases and a broad spectrum of disorders are assumed to be treated by altering the function of the immune system. For this reason, immunotherapy has attracted a great deal of attention and numerous studies on different approaches for immunotherapies have been investigated, using multiple biomaterials and carriers, from nanoparticles (NPs) to microneedles (MNs). In this review, the immunotherapy strategies, biomaterials, devices, and disea...

Building a Digital Immune System
Credit: Courtesy of Dr. Tomas Helikar. The power of computer code has been a longtime fascination for Tomas Helikar, Ph.D., a professor of biochemistry at the University of Nebraska-Lincoln (UNL). In college, when he learned he could use that power to help researchers better understand biology and improve human health, Dr. Helikar knew he’d found his ideal career. Since then, he’s built a successful team of scientists studying the ways we can use mathematical models in biomedical research, such as creating a digital replica of the immune system that could predict how a patient will react to infectious microorganisms ...

In conclusion, among Swedish middle-aged subjects, nearly two-thirds showed complete fatty degeneration of thymus on CT. Age-Related Dysfunction of Water Homeostasis https://www.fightaging.org/archives/2023/06/age-related-dysfunction-of-water-homeostasis/ Dehydration can be an issue in older people. As in every complex system in the body, the mechanisms by which hydration is regulated become dysfunctional with advancing age. Researchers here look at the brain region responsible for regulating some of the response to dehydration, cataloging altered gene expression in search of the more important mechani...

Production of monoclonal antibodies for therapeutic purposes: A review
Int Immunopharmacol. 2023 May 25;120:110376. doi: 10.1016/j.intimp.2023.110376. Online ahead of print.ABSTRACTMonoclonal antibodies (mAbs) have been used in the development of immunotherapies that target a variety of diseases, such as cancer, autoimmune diseases, and even viral infections; they play a key role in immunization and are expected after vaccination. However, some conditions do not promote the development of neutralizing antibodies. Production and use of mAbs, generated in biofactories, represent vast potential as aids in immunological responses when the organism cannot produce them on their own, these convey un...

Coronavirus Disease-2019 in the Immunocompromised Host
Clin Chest Med. 2023 Jun;44(2):395-406. doi: 10.1016/j.ccm.2022.11.012. Epub 2022 Nov 22.ABSTRACTImmunocompromised hosts, which encompass a diverse population of persons with malignancies, human immunodeficiency virus disease, solid organ, and hematologic transplants, autoimmune diseases, and primary immunodeficiencies, bear a significant burden of the morbidity and mortality due to coronavirus disease-2019 (COVID-19). Immunocompromised patients who develop COVID-19 have a more severe illness, higher hospitalization rates, and higher mortality rates than immunocompetent patients. There are no well-defined treatment strateg...

History of the discovery and development of Biomodulina T (InmunyVital ®), a useful immunomodulator with a broad range of clinical applications
This article identifies the milestones involved in the development of Biomodulina T. Since its discovery more than 35 years ago, reports show that Biomodulina T is a modulator of immune response and inflammation that is very useful for restoring the immune system in young and elderly people with immunodeficiencies, autoimmune diseases, and infections. Biomodulina T is also useful as an immunotherapeutic agent for improving immune responses in cancer and vaccines, for reversing immunosenescence and for improving healthspan in aging.PMID:37086680 | DOI:10.1016/j.intimp.2023.110167

Epigenetic liquid biopsies: a novel putative biomarker in immunology and inflammation
Trends Immunol. 2023 Apr 1:S1471-4906(23)00049-2. doi: 10.1016/j.it.2023.03.005. Online ahead of print.ABSTRACTImmune and inflammatory processes occurring within tissues are often undetectable by blood cell counts, standard circulating biomarkers, or imaging, representing an unmet biomedical need. Here, we outline recent advances indicating that liquid biopsies can broadly inform human immune system dynamics. Nucleosome-size fragments of cell-free DNA (cfDNA) released from dying cells into blood contain rich epigenetic information such as methylation, fragmentation, and histone mark patterns. This information allows to inf...
