										<content:encoded><![CDATA[<p style="font-weight: 400;"><strong>Alpha-1 History Video: When Medical History Comes Alive</strong></p>
<p>A contribution by Leyla Gür.</p>
<p style="font-weight: 400;">There are projects in our agency work that feel special right from the initial discussions. The video about the history of alpha-1 antitrypsin deficiency was exactly that kind of project for me. It quickly became clear: this wasn&#039;t just going to be a nice piece of social media content. This was about a story that has moved people for more than 130 years and that still holds great significance for medicine in general today.</p>
<p style="font-weight: 400;">But let&#039;s start from the beginning. Last year, I had the opportunity to speak with Prof. Dr. Sabina Janciauskiene and Marion Wilkens about the history of Alpha-1 antitrypsin deficiency, on behalf of Alpha1 Germany e.V. Prof. Dr. Janciauskiene serves as a scientific advisor to Alpha1 Germany and has been conducting research on Alpha-1 for many years. Marion Wilkens, as you all probably know, is passionately and tirelessly committed to supporting those affected by Alpha-1, their families, and raising awareness of Alpha-1, both in Germany and internationally.</p>
<p>We were then able to turn this conversation into a video, which is now finally available for you to watch and listen to – on YouTube and also on Spotify. Feel free to take a look.</p>
<p style="font-weight: 400;"><a href="https://www.youtube.com/watch?v=q1u6npwXL_E&amp;t=2980s" target="_blank" rel="noopener">Go to YouTube</a></p>
<p><a href="https://open.spotify.com/episode/1efNHlVg4gw2FUZlCjp9ki" target="_blank" rel="noopener">Go to Spotify</a></p>
<p style="font-weight: 400;"><strong>A discovery with consequences</strong></p>
<p style="font-weight: 400;">One thing I learned during the preparation with Sabina and Marion, and which I&#039;d like to share as a little spoiler: The story of Alpha-1 goes far beyond the disease itself. It also tells of how medicine evolves and how individual observations can gradually form a larger picture – and why it&#039;s worth taking a closer look when symptoms don&#039;t quite fit the usual explanations.</p>
<p style="font-weight: 400;">In the video, Sabina takes us back to the 19th century, to the first traces of Alpha-1. At that time, terms like DNA, genes, or protein variants, as we understand them today, didn&#039;t yet exist. Nevertheless, researchers at that time observed that substances apparently existed in the blood that could inhibit certain protein-degrading enzymes.</p>
<p style="font-weight: 400;">The decisive breakthrough came in the early 1960s when the two Swedish researchers Carl-Bertil Laurell and Sten Eriksson, using new laboratory methods, were able to demonstrate that some patients with early-stage pulmonary emphysema lacked a specific protein: alpha-1-antitrypsin. This proved to be a far-reaching discovery! It suddenly made it clear why even people without the classic risk factors such as smoking or occupational exposure to particulate matter can develop severe lung damage – and just how incredibly versatile and important proteins in our bodies truly are.</p>
<p style="font-weight: 400;">But I don&#039;t want to give too much away. In the video, you&#039;ll learn, among other things, which scientific breakthroughs made this discovery possible, why alpha-1 antitrypsin still plays such an important role in medicine today, and how closely research, education, and personal experiences are intertwined.</p>
<p style="font-weight: 400;"><strong>Camera and action – My impressions from the filming day</strong></p>
<p style="font-weight: 400;">What I found particularly wonderful about filming this historical video was the location itself. Being able to film at the Thorax Clinic in Heidelberg was a perfect thematic fit. Many people actively involved in Alpha-1 research work and conduct research here today – including Prof. Dr. Franziska Trudzinski. At the same time, the clinic has stood for decades for pulmonary medicine and pioneering research. Special thanks go to Mr. Frank, Prof. Dr. Herth, Dr. Oswinde Bock-Hensley, and the entire Thorax Clinic team for their great openness and for even allowing us to use the Tuberculosis Museum located in the small castle as a filming location.</p>
<p style="font-weight: 400;">Everything went perfectly on location. Our cameraman, Martin Sauer from entermedia, brought everything needed for a professional shoot – from cameras and lights to sound equipment, tripods, and a whole lot of cables. Before the actual interview could begin, everything was carefully set up, wired, and tested. Microphones were attached, transmitters stowed away, and every detail checked multiple times. What looks so easy in the video actually requires a bit of planning and work.</p>
<p style="font-weight: 400;">The conversation went not only smoothly and with great professionalism, but was also very impressive to me both in terms of content and personality. Even though I was already familiar with the topics through my preparation, it was more than inspiring to see how much energy, knowledge, and passion Marion and Sabina radiate. It made me realize once again that with illnesses like Alpha-1, it&#039;s never just about medical facts, but always about people – people who are affected, but also people who are committed and full of enthusiasm to ensuring that the former are seen, understood, and supported in the best possible way.</p>
<p style="font-weight: 400;"><strong>Far from being from yesterday: Why history can give hope</strong></p>
<p style="font-weight: 400;">But why did we actually make a video about the history of Alpha-1? Isn&#039;t there much more exciting stuff to tell about from the here and now?</p>
<p style="font-weight: 400;">Of course, first of all, one must say: A video is only <em>a</em> Video. And we very much hope to be able to implement many more videos and formats in the future, which deal, for example, with current research approaches, new developments or personal stories.</p>
<p style="font-weight: 400;">At the same time, the story of Alpha-1 is much more than just a look back. It can still provide valuable insights today and perhaps even offer hope. Thanks to the special perspectives of Marion and Sabina, who have accompanied and, in some cases, actively shaped the development of Alpha-1 over many years, it becomes clear what has already been achieved. One realizes how many people have contributed to the fact that we know so much more about the disease today than we did just a few decades ago.</p>
<p style="font-weight: 400;">This also makes it clear that progress is rarely linear. Sometimes it&#039;s new technological possibilities, sometimes lucky coincidences, and often years of hard work that make the crucial difference. And sometimes it takes the courage to follow a path that doesn&#039;t seem particularly promising at first glance.</p>
<p style="font-weight: 400;">Perhaps that&#039;s precisely why history is so encouraging: it shows that developments take time and that progress is built on the knowledge and commitment of many different people. Nothing comes from nothing, and to sharpen the analogy even further: only when you look back do you see how far you&#039;ve actually come – regardless of how much road still lies ahead.</p>
<p style="font-weight: 400;">So, if you ask me: Take a quiet minute – or better yet, 60. <img src="https://s.w.org/images/core/emoji/17.0.2/72x72/1f609.png" alt="😉" class="wp-smiley" style="height: 1em; max-height: 1em;" /> And take a look at the story of Alpha-1, as told by Marion and Sabina. Perhaps it will make it as clear to you as it did to me that looking back not only explains how we got here, but also shows what becomes possible when people work on something with curiosity, perseverance, and dedication for many years. I definitely give it my highest recommendation!</p>

										<content:encoded><![CDATA[<h1 style="font-weight: 400;"><span style="color: #004267;"><strong>New guideline for follow-up care after lung transplantation</strong></span></h1>
<h2 style="font-weight: 400;"><span style="color: #004267;"><strong>Greater safety and clear recommendations for patients</strong></span></h2>
<p style="font-weight: 400;">For people who have undergone lung transplantation, good and regular follow-up care is crucial. To provide doctors with the best possible support, a so-called [missing word - likely &quot;care plan&quot;] was launched worldwide for the first time in November 2025. <strong>S3 guideline on follow-up care for adult lung transplant recipients</strong> published.</p>
<p style="font-weight: 400;">This guideline was developed under the leadership of <strong>German Society for Pneumology and Respiratory Medicine (DGP)</strong>Developed jointly with other professional societies from Germany, Austria, and Switzerland, it summarizes the current state of scientific knowledge and provides clear recommendations on how medical care should be provided after a lung transplant.</p>
<p style="font-weight: 400;">The focus is on a <strong>structured follow-up plan</strong>. It describes,</p>
<ul style="font-weight: 400;">
<li>which examinations are important after transplantation,</li>
<li>how often checks should take place (e.g. frequent at first, later at longer intervals),</li>
<li>and how possible complications can be detected early.</li>
</ul>
<p style="font-weight: 400;">The aim of the guideline is to... <strong>Long-term health and quality of life</strong> to improve the care of lung transplant patients and to ensure the most uniform, high-quality care possible.</p>
<p style="font-weight: 400;"><strong>Regarding the DGP press release:</strong><br />

	<p><strong>„&quot;AAT supports the immune response and plays an important role in the course of inflammation, infection or tissue injury.&quot;“</strong></p>
<p>Proteins are essential for our bodies, as they are responsible for a multitude of cellular functions. Some proteins provide the structure of the cell. Others act as transporters for smaller molecules, such as hemoglobin in red blood cells, which carries oxygen to the cell and carries away carbon dioxide. Enzymes are needed to initiate or accelerate biochemical reactions in the body. Antibodies enable the body&#039;s immune system to recognize and specifically combat potentially harmful microbes.</p>
<p>Alpha-1-antitrypsin (AAT) is an acute-phase protein. AAT supports the immune response and plays an important role in the course of inflammation, infection, or tissue injury. AAT is primarily produced in the liver and is found in virtually all body tissues. It acts as a protective protein, serving as an important antagonist to endogenous substances that can break down tissue.</p>
<p>Although proteins perform a wide variety of functions, they are all structured according to a basic principle. They consist of various amino acids (building blocks) strung together like beads on a necklace and linked by a peptide bond between the carboxyl group (one end of an amino acid) of the first and the amino group (the other end of an amino acid) of the next. Depending on which of the 20 amino acids are used and in what order they are linked, different proteins are formed. Each protein has a very specific three-dimensional structure. This structure is essential for the protein to perform its specific function within the organism.</p>
<p>The blueprints for proteins are stored in DNA (deoxyribonucleic acid) segments (genes) in the form of a code (genetic code). The genetic code is derived from the sequence in which the four organic bases adenine, thymine, cytosine, and guanine are arranged.</p>
<p>The process from gene to protein is called protein biosynthesis and consists of two main steps: transcription and translation (see Fig. 1 ‚From gene to protein‘).</p>
<p>During transcription (from Latin transcribere = to transcribe), transportable copies (mRNA = messenger RNA) of the DNA segment that codes for the protein are produced in the cell nucleus. For this purpose, the genetic information of the double-stranded DNA is transcribed into single-stranded mRNAs. In the RNA, the base thymine is replaced by the base uracil.</p>
<p>After transcription, the mRNA is transported from the cell nucleus into the cytoplasm and binds to the ribosome, where it is translated. Here, the mRNA serves as a template for linking different amino acids together to form a protein.</p>
<p>Three consecutive bases, also called triplets or codons, code for one amino acid. In addition, there are special combinations (codons) for the beginning (start) and end (stop) of a gene (see Fig. 2, &#039;Genetic Code Chart&#039;). This code is – with few exceptions – universal: in humans, mice, and bacteria.</p>
<p>The deciphering of the genetic code in 1961 by Nirenberg and Matthaei made it possible to understand the processes of protein biosynthesis at the molecular level, thus forming the foundation of genetic engineering (MW Nirenberg, JHMatthaei, Proc. Natl. Acad. Sci. USA 1961, 47, 1601. 6) Cold Spring Harbor Symposium, Vol. XXXI, 1966, pp. 25-38).</p>
<p>Currently, various groups worldwide are researching diverse applications of &#039;medical&#039; RNA: this ranges from the treatment of hereditary diseases and cancers to vaccination.</p>
<p>Studies in the field of alpha-1 antitrypsin deficiency also utilize RNA interference (RNAi) to selectively silence genes. RNAi is a natural mechanism in cells used to silence genes. RNA interference is based on the interaction of short RNA fragments with mRNA. As a result, the mRNA is cleaved into multiple fragments, and the information it carries is disrupted. Translation into a protein is prevented. This allows the cell to regulate protein production, as not every cell needs the same proteins at the same time.</p>
<p>This mechanism is being used in a study of patients with alpha-1 antitrypsin deficiency and the Pi*ZZ genotype. In the common Z mutation, alpha-1 antitrypsin is misfolded and cannot diffuse from liver cells into the bloodstream. An artificially produced RNA fragment is intended to inhibit the production of the mutated alpha-1 antitrypsin (Z-AAT) protein, thus preventing the accumulation of misfolded Z proteins in liver cells. The current state of the study looks very promising. (Strnad P, Mandorfer M, et al. Fazirsiran for Liver Disease Associated with Alpha(1)-Antitrypsin Deficiency. N Engl J Med. 2022 Aug 11;387(6):514-524. doi: 10.1056/NEJMoa2205416. Epub 2022 Jun 25.)</p>
