Hungarian scientists revealed the 3D structure of a key protein
The scientific research is constantly seeking new ways to deepen our understanding of biological systems and the functioning of molecules. One of the most significant breakthroughs in the field of biomolecular sciences in recent times is the discovery of cryo-electron microscopy, which is revolutionizing biochemical and immunological research. With this method, researchers can map the three-dimensional structure of proteins in detail, which can fundamentally influence drug development and disease treatment. Proteins are key players in the functioning of our cells, and the information coded by DNA only specifies the sequence of amino acids. To truly understand the functions performed by proteins, it is important to know how they bend and…

How do immunoglobulins work?
Az immunglobulinok, más néven immunoglobulinok, a szervezet immunrendszerének kulcsszereplői, amelyek a B limfociták, azaz a fehérvérsejtek egy fajtája által termelődnek. Ezek a glikoproteinek elengedhetetlenek a humorális immunválasz kialakulásában, amely a szervezet védelmét szolgálja a kórokozókkal szemben. Az immunglobulinok működése alapvetően azon alapul, hogy képesek specifikus módon kötődni a különböző antigénekhez, azaz a kórokozók felületén található fehérjékhez, ezzel aktiválva az immunválaszt. Az immunglobulinok szerepe a kórokozók ellen A szervezetben bármilyen kórokozó, például baktériumok, vírusok, gombák vagy paraziták ellen termelődhetnek immunglobulinok. Ezek a fehérjék nemcsak a fertőzések leküzdésében játszanak szerepet, hanem az allergiás reakciókban és autoimmun folyamatokban is, amikor a szervezet saját sejtjeit is idegenként ismeri fel. Az immunglobulinok termelődése a vérkeringésben,…

Blood Calcium as a Laboratory Indicator
A calcium is one of the most important minerals in the human body, with the majority found in the bones. This substance is essential for maintaining the health of bones and teeth, but its role extends far beyond the skeletal system. Calcium ions in the blood exist in three main forms: bound to proteins, forming complexes with various negatively charged ions, and in free, ionized form. The level of calcium in the body is extremely important, as it influences the processes of the nervous system, heart function, and muscle contraction. The proper balance of calcium levels in the blood is essential for the uninterrupted functioning of various physiological functions. Adhering…

Potassium Ion – What Information is Important Regarding Its Laboratory Results?
The concentration of potassium ions is a key indicator of the body’s fluid and electrolyte balance, and understanding it is essential for maintaining health. Potassium, as the positively charged ion present in the highest amounts within cells, plays a fundamental role in nerve and muscle function, including the functioning of the heart muscle. The level of potassium ions in the blood is tightly regulated and can only vary within narrow limits under normal circumstances. The concentration of potassium ions is influenced by several factors, such as the ratio of sodium and hydrogen ions, as well as the functioning of the kidneys and the gastrointestinal tract. Additionally, certain medications and dietary…
