The mechanism by which G protein mutations lead to excessive activation of T cells through non classical pathways

Writing | Snow Moon G protein coupled receptors (GPCRs) guide cellular responses to environmental signals, including hormones, neurotransmitters, and chemokines. This process is achieved through a complex biochemical cycle mediated by heterotrimeric G protein. After GPCR binds to the ligand, the G α subunit binds to GTP, becomes active, and separates from the G β – γ complex and GPCR. The separated G α – guanosine triphosphate (GTP) and free G β – γ initiate downstream signaling, including the generation of second messengers, biochemical interactions, and ion channel changes. The GTPase activity of G α hydrolyzes GTP to guanosine diphosphate (GDP), thereby terminating signal transduction and allowing Gabg to reassemble with GPCRs, enabling cells to respond to reactivation of GPCRs. In the G α protein family, the Gai/o family includes inhibitory subtypes that regulate biological responses by inhibiting the production of cyclic adenosine monophosphate (cAMP) by adenyl cyclase AC. AC ...

RNA editing pioneers fought a comeback

“CRISPR gives way, RNA editing therapies are going to speed up.” This is the title of an article published in “Nauter” in February this year (“Move over, CRISPR: RNA-editing therapies pick up steam”). RNA editing technology, which is coming to the fore, is seen as having the potential to surpass CRISPR due to its safer and more flexible characteristics. The technology is in its infancy, and the bets of MNCs such as Eli Lilly and GSK have once pushed its popularity to a climax. However, Wave, an RNA editing pioneer founded in 2012, took more than 10 years to push its first RNA editing project WVE-006 into clinical trials. During this period, due to the clinical failure of other nucleic acid drugs, Wave’s stock price fell from a high of US$56 per share to around US$1 per share, and market expectations were no longer there. After years of silence, a ...

Astellas wins a belated victory

On October 18, the FDA announced the approval of the Claudin18.2 monoclonal antibody Vyloy (zolbetuximab) for marketing, and will use it as the first-line treatment for adult patients with locally advanced unresectable or metastatic gastric cancer with Claudin18.2-positive tumors, and HER2-negative gastroesophageal junction adenocarcinoma. With the announcement of this good news, zolbetuximab officially became the first anti-Claudin18.2 drug approved by the United States. This means that Astellas has taken the lead in this hot target. In the past few years, Claudin18.2 has been a hot target in the field of oncology, attracting the interest of giants such as AstraZeneca, Merck, and Moderna. Of course, the entrants also include many domestic pharmaceutical companies. However, in the face of many entrants, Astellas’s “defending” ability has also been extremely demanding. At present, it may not be easy for it to maintain its leading position. Zolbetuximab has always attracted much attention, and the core ...

400,000 patients don’t want to lose their bladders

Protecting the bladder is definitely a topic worth paying attention to for pharmaceutical companies. The core reason is that there are many patients who face the decision of whether to keep their bladders. Bladder cancer is the tenth most common cancer in the world, with more than 614,000 new cases of bladder cancer in 2022. About 70% of patients are initially diagnosed with non-muscle invasive bladder cancer (NMIBC), corresponding to a population of more than 400,000. According to the severity, NMIBC can be divided into carcinoma in situ (CIS) that only exists on the surface of the bladder, non-invasive papillary carcinoma (Ta), and tumors that invade the lamina propria (T1). Fortunately, bladder cancer has obvious early symptoms, which facilitates early detection and early treatment. In the past few decades, the standard treatment for NMIBC has been transurethral resection of bladder tumors (TURBT) plus postoperative adjuvant intravesical instillation of BCG. Unfortunately, ...

Yuyue Medical’s “wishful thinking”

The performance of the leading player ResMed fully reflects this point. In fiscal year 2024, ResMed’s equipment revenue alone reached US$2.444 billion. As another example of the “razor + blade” model, the revenue brought by home ventilators is not limited to equipment. In fiscal year 2024, in addition to equipment, ResMed’s consumables revenue reached US$1.657 billion, a year-on-year increase of 14%, which is much higher than the equipment; and ResMed also opened up the space for the SAAS business model, with revenue reaching US$584 million, a year-on-year increase of 17%. Under the three-wheel drive model of equipment, consumables, and software, ResMed’s total revenue in fiscal year 2024 reached US$4.685 billion and its net profit reached US$1.021 billion. In the huge medical equipment industry, such a scale is not considered the top, but it must not be ignored in the subdivided field. The outstanding performance of the leader naturally attracted the ...

Milepost! The first RNA editing therapy releases clinical data

On October 16th, Wave Life Sciences released positive mechanistic evidence data from the Ib/IIa RestorAATion-2 study of RNA editing therapy WVE-006 for the treatment of alpha-1 antitrypsin deficiency (AATD). This is the first RNA editing therapy to release clinical data. AATD is a genetic disease caused by mutations in the SERPINA1 gene, which encodes alpha-1 antitrypsin (AAT), the most abundant protease inhibitor in human serum. Patients with homozygous protease inhibitor gene mutation type (Pi * ZZ) AATD are unable to naturally produce wild-type alpha-1 antitrypsin (M-AAT) protein. Therefore, after receiving WVE-006 treatment, patients can produce M-AAT protein in their bodies, which confirms the successful editing of mutant Z-AAT mRNA. In addition, restoring 50% of M-AAT levels will be consistent with the heterozygous “MZ” genotype, resulting in a lower risk of AATD lung disease and liver disease. The data released this time comes from the 200mg single dose cohort of RestorAATion-2 ...

90%! Pfizer’s RSV vaccine has significant efficacy in treating severe respiratory diseases

The new data released on Thursday at IDWeek provides a clearer picture of Abrysvo’s performance in preventing severe illness and hospitalization. The results came from Kaiser Permanente in Southern California, although the trial was funded by Pfizer and included co authors from Pfizer. This retrospective study observed patients aged 60 and above who were hospitalized or visited the emergency room due to severe acute respiratory disease. In this group, the effectiveness of the vaccine in preventing the most severe respiratory cases was 90%, with only one positive case found among patients who received the Abrysvo vaccine. The confidence interval is wide, ranging from 24% to 99% in preliminary analysis. Although the results were not significantly different from those shown by the company in previous trials, this study is the first to review individuals with compromised immune function as they were not included in the Phase 3 study. Despite the introduction ...
