Magnesium and its function for immune defense

Magnesium is an essential mineral involved in over 300 enzymatic reactions in the human body and plays a significant role in immune system function. As a cofactor for numerous biochemical processes, magnesium supports cell function, energy production, and the regulation of immune responses. This article explores the immunological functions of magnesium, the underlying mechanisms, and the clinical consequences of magnesium deficiency. Magnesium in the Immune System: Basic Mechanisms Magnesium influences both innate and adaptive immunity through its involvement in cellular processes, signal transduction, and inflammation regulation. The main mechanisms can be summarized as follows: Magnesium Deficiency and Immune Defense Magnesium deficiency has far-reaching effects on immune function, increasing susceptibility to infections and the risk of chronic inflammatory diseases. Consequences of magnesium deficiency include: Magnesium deficiency is widespread globally, particularly among the elderly, individuals with unbalanced diets, and those with chronic diseases (e.g., diabetes, malabsorption)… 

Selenium and its function for immune defense

  • News

Selenium is an essential trace element that plays a central role in maintaining an effective immune response. As an integral component of selenoproteins, which perform enzymatic and structural functions in the human body, selenium is involved in numerous processes that support innate and adaptive immunity. This article highlights the immunological functions of selenium, the underlying mechanisms, and the clinical implications of selenium deficiency. Selenium in the Immune System: Basic Mechanisms Selenium primarily acts through its integration into selenoproteins, of which approximately 25 have been identified in the human body. These proteins, such as glutathione peroxidases (GPx), thioredoxin reductases, and selenoprotein P, are crucial for immune function. The main mechanisms can be summarized as follows: Selenium Deficiency and Immune Defense Selenium deficiency significantly impairs immune function, increasing susceptibility to infections and the severity of inflammatory diseases. Consequences of selenium deficiency include: Selenium deficiency often occurs in regions with selenium-poor soils,… 

Zinc and its function for immune defense

  • News

Zinc is an essential trace element that plays a central role in numerous physiological processes of the human body, particularly in the function of the immune system. As a cofactor for over 300 enzymes and a component of more than 3,000 proteins, zinc influences a variety of cellular processes that are crucial for maintaining effective immune defense. This article highlights the importance of zinc for immune function, the underlying mechanisms, and the clinical implications of zinc deficiency. Zinc in the Immune System: Basic Mechanisms Zinc is involved in almost all aspects of the immune response, in both innate and adaptive immunity. It acts as a regulator of immune cell function, influences signal transduction, and supports the barrier function of the skin and mucous membranes. The main functions can be summarized as follows: Zinc Deficiency and Immune Defense Zinc deficiency has far-reaching effects on immune function. Clinical studies show that even marginal zinc deficiency…

Blood fats cause dementia

  • News

People at increased risk for heart disease also seem to develop dementia more often. A study led by the University of Texas Health Science Center at San Antonio (UT Health San Antonio) has uncovered new links between different blood lipid, or fat, levels and the risk of Alzheimer’s disease, the most common cause of dementia worldwide. The findings mean that blood fat profiles could help better understand, predict, and possibly even prevent the disease in the future. In more than 800 older adults who participated in the long-running Framingham Heart Study, researchers found that higher levels of small, dense cholesterol particles – known to increase the risk of atherosclerosis and coronary heart disease – were linked to a higher risk of Alzheimer’s. However, higher levels of a marker for small fat-carrying particles involved in transporting dietary fats from the gut through the blood to other body tissues after eating were associated with a lower…

European University Alliance FORTHEM Signs Joint Palermo Declaration Defending Academic Freedom

  • News

Joint Declaration by FORTHEM Alliance Universities Reaffirms Shared Responsibility to Protect Autonomy and Integrity of Higher Education and Research in Europe and Beyond: In recent months, we have witnessed growing threats to the autonomy and integrity of higher education and scientific research worldwide. In a number of countries, state actors have begun to question the standards of scientific truth, seeking to pursue political or commercial interests at the expense of rigorous, independent research. This pressure manifests in attempts to restrict academic freedom by cutting research funding for certain topics, for example in the social sciences and humanities, or by discontinuing established protocols for longitudinal research, particularly on environmental topics. Initiatives to promote diversity, equity, and inclusion have been specifically attacked and delegitimized. This occurs within a broader societal, political, and media landscape characterized by widespread disinformation, where…
