Virus-like particles (VLPs) are nano-sized particles formed by the self-assembly of viral structural proteins. They lack the viral genetic material, are non-infectious, and exhibit an excellent safety profile. VLPs mimic the native conformation and repetitive surface antigen array of viruses, enabling potent activation of both B cells and T cells. Consequently, they are widely used in vaccine development and antigen presentation. Researchers can produce VLPs in the laboratory by expressing recombinant viral proteins in various expression systems, including prokaryotic cells, yeast, insect cell lines, plant cells, and mammalian cell lines

On October 6th local time, the Karolinska Institute in Sweden announced that the 2025 Nobel Prize in Physiology or Medicine would be awarded to American scientists Mary E. Brunkow, Fred Ramsdell, and Japanese scientist Shimon Sakaguchi, in recognition of their groundbreaking discoveries concerning peripheral immune tolerance. The laureates will share the prize money of 11 million Swedish kronor.

Recently, a team led by Michael Demetriou at the University of California, Irvine, published a study in Cell titled "Safe immunosuppression-resistant pan-cancer immunotherapeutics by velcro-like density-dependent targeting of tumor-associated carbohydrate antigens." The research team proposed a novel, broad-spectrum cancer immunotherapy strategy. By achieving "Velcro-like" high-affinity targeting of Tumor-Associated Carbohydrate Antigens (TACAs), they enabled efficient killing of various cancers while avoiding the "on-target, off-cancer" toxicity common in traditional immunotherapies. This approach offers new therapeutic hope for solid and hematological tumors that currently lack effective targets.

In the field of immunology, immunoglobulin G (IgG) is widely regarded as the workhorse of humoral immunity. As the most abundant antibody in mammalian serum, it plays a critical role in defending against pathogenic infections.

A study published in Advanced Science in September 2025, titled "PVC Nanoplastics Exposure Exacerbates Asthma through R-Loop Accumulation and Subsequent STING Activation in Macrophages", systematically reveals a novel mechanism by which PVC nanoplastics aggravate asthmatic inflammatory responses by promoting R-loop accumulation and activating the cGAS-STING pathway in macrophages.

Model organisms are species used to study and reveal biological phenomena that follow universal patterns in living systems. In simple terms, due to ethical and practical constraints, life science research often cannot be conducted directly on humans or within complex ecosystems. To uncover fundamental principles of life or physiological mechanisms, scientists rely on organisms that are highly representative and experimentally tractable—these are model organisms.

Globally, measles cases are trending upwards in North America, the European Union, and the United Kingdom. The United States is currently facing its most severe measles outbreak since declaring the disease eliminated in 2000. According to the latest data released by the Centers for Disease Control and Prevention (CDC) on the 22nd, the U.S. has reported 1,618 confirmed measles cases so far this year, resulting in 198 hospitalizations and 3 deaths. This marks the highest number of confirmed cases in the past 33 years, surpassing the previous record of 1,274 cases set in 2019. The outbreak primarily affects children under five years of age, with approximately 92% of patients being unvaccinated or having an unknown vaccination status.

October 29th each year marks World Stroke Day. Established by the World Stroke Organization (WSO), it was initiated in 2006 and officially launched in 2007. This day aims to raise global awareness about stroke—a preventable and treatable disease—and to mobilize governments, healthcare institutions, and the public to take preventive and treatment measures. The global core slogan set by WSO for 2025 is "Every Minute Counts. Know the signs of stroke. Act FAST."

The 2025 Northern Hemisphere influenza season is characterized by a notably early onset. Surveillance data from both domestic and international sources indicate that the Influenza A(H3N2) virus has become the predominant circulating strain, presenting a challenging prevention and control situation.

Every September is World Alzheimer’s disease (AD) Month， AD is a neurodegenerative disorder characterized pathologically by the deposition of amyloid β-protein (Aβ) and hyperphosphorylation of tau protein. It clinically manifests as cognitive impairment, neuropsychiatric symptoms, and loss of social functioning. AD as the most common neurodegenerative disorder, has become a major global public health challenge. According to statistics, approximately 55 million people worldwide are currently living with AD, and this number is projected to exceed 130 million by 2050, with over 60% of patients residing in developing countries. In terms of disease burden, global healthcare expenditures related to AD surpassed $1.3 trillion in 2023, and with an aging population, this cost continues to grow at an annual rate of 10%.

Cervical cancer ranks as the fourth most common cancer among women globally and is caused by persistent infection with the Human Papillomavirus (HPV), a small DNA virus known to infect the skin, genital areas, and throat. Based on disease severity, HPV is categorized into low-risk and high-risk types. Persistent infection with high-risk HPV, particularly types 16 and 18, is responsible for 70% of cervical cancer cases due to their potential to cause malignant tumors.
