What the paper reports

Acid-cleavable cholesterol-derived crosslinkers and PEG-diamines stabilized anionic LNPs that otherwise lost activity during purification. By tuning crosslinking architecture, researchers balanced structural integrity with RNA release and improved splenic mRNA expression. Mechanistic analyses implicated intracellular processing as well as release behavior. These formulation-specific animal results do not establish general T-cell targeting or clinical manufacturing readiness.

Why this paper is included

Expands accessible anionic formulation space for spleen delivery; crosslinker clearance, repeat dosing, and manufacturing comparability still need evaluation.

The interpretation above is analysis, not a conclusion attributed to the original source.

Moderna raises 2026 revenue outlook after third-quarter growth

Moderna reported third-quarter 2026 revenue of $1.3 billion, up 29% year over year, and GAAP net income of $162 million, compared with a $200 million loss a year earlier. It raised expected full-year revenue growth to 15%–25% from up to 10%. The company attributed quarterly growth mainly to international COVID vaccine sales supported by government partnerships.

Ethris reports exploratory antiviral and exposure-response signals for nasal ETH47 in asthma

Ethris reported topline results from a randomized Phase 2a rhinovirus-challenge study involving 50 adults with asthma. A single nasal dose of ETH47, an interferon-lambda-encoding mRNA candidate, produced local expression and lower day-two viral load. Symptom improvements were described as numerical trends; exposure-response subgroup findings remain exploratory, without established clinical efficacy.

Moderna reports initial mRNA-2808 T-cell engager results in multiple myeloma

Moderna reported initial Phase 1/2 MyEngage findings for mRNA-2808, which encodes three T-cell engagers. Four confirmed responses occurred among 11 response-evaluable patients. Twelve patients had received treatment; Grade 3 or higher treatment-related adverse events occurred in 41.7%. These small, uncontrolled findings are preliminary and do not establish comparative benefit.
