Recent research indicates that Clostridium butyricum MIYAIRI 588 (CBM588), a probiotic, may enhance immune responses in cancer patients, particularly those undergoing immune checkpoint inhibitor therapy. The findings suggest that patients receiving this probiotic could experience improved response rates and overall survival.

CBM588 has a long history of use in Japan, dating back to the 1960s, primarily for treating gastrointestinal disturbances. Its established safety record includes applications in young children and during pregnancy, making it a promising candidate for further research in oncology.

In the study, researchers identified a specific immune cell population, Vγ9Vδ2 T-cells, activated by CBM588. Notably, higher activation of these T-cells in lung cancer patients correlated with better treatment outcomes, indicating a potential mechanism through which the probiotic may exert its effects.

Dr. Garry Dolton noted, “Several recent studies have shown that the gut microbiome is linked to how well patients respond to checkpoint blockade therapy,” emphasizing the growing interest in the relationship between gut health and cancer treatment efficacy.

Professor Chihiro Motozono from Kumamoto University remarked, “Our colleagues in Kumamoto observed encouraging clinical results with CBM588, but the key question was how it was benefiting patients.” This highlights the need for further investigation into the biological mechanisms at play.

Professor Andrew Sewell added, “This study moves us from an association between the gut microbiome and cancer treatment outcomes to a defined immune pathway,” suggesting a significant advancement in understanding how probiotics may influence cancer therapy.

The research was supported by various institutions, including Cardiff University, Kumamoto University, AMED Research Programs, the Wellcome Trust, and Cancer Research Wales. However, details remain unconfirmed regarding the exact biological mechanisms through which CBM588 affects immune responses.

Furthermore, the clinical analyses conducted to date have been modest in size, indicating that further prospective trials are necessary to validate these findings and explore the full potential of CBM588 in cancer immunotherapy.

Leonid Radvinsky, the billionaire owner of OnlyFans, has died from cancer at the age of 43. His passing, which occurred on March 24, 2026, was confirmed by a spokesperson for the company.

Radvinsky’s death was not made public immediately after he passed; he had died several days earlier. Insiders were aware of his health issues for some time, but the news of his death has nonetheless come as a shock to many.

Radvinsky acquired Fenix International Limited, the parent company of OnlyFans, in 2018 and transformed the pornography industry with the platform’s subscription-based model. OnlyFans allows creators to charge directly for their content, retaining 20% of their earnings.

Under Radvinsky’s leadership, OnlyFans reportedly generated $7.4 billion in revenue, particularly seeing a surge during the pandemic when the platform added approximately 300,000 users daily. His innovative approach reshaped the economics of the adult content industry, enabling creators to reach audiences directly.

Born in Ukraine and raised in Chicago, Radvinsky studied economics at Northwestern University. He was also known for his philanthropic efforts, including a $23 million grant for cancer research supported by him and his wife, Yekaterina ‘Katie’ Chudnovsky.

Before his death, Radvinsky lived in a $19 million oceanfront condominium in Miami. His only known public photo is from a gala event in 2024, highlighting his preference for a private life despite the public nature of his business.

Andy Bachman, a close associate, remarked, “Insiders knew [Radvinsky] had been dealing with health issues for some time, and while his passing is tragic, he left behind a company that was fully prepared and resilient.”

Another industry figure, Sophie Rain, expressed gratitude for Radvinsky’s contributions, stating, “I will never forget that. That platform gave me everything. And that doesn’t happen without someone building it in the first place.”

Radvinsky’s legacy will likely continue to influence the adult content industry for years to come, as he has left a significant mark on how creators monetize their work.
