Publication number: 20250114298Abstract: The subject invention pertains to a long-term antigen depot that can bypass FBR and engage DCs to mature and migrate to lymph nodes to activate antigen-specific T-cell activations. Leveraging on the immunomodulatory properties of exogenous polysaccharides and the anti-fouling characteristics of zwitterionic phosphorylcholine (PC) polymer, the invention features a PC functionalized dextran (PCDX) hydrogel for long-term antigen delivery. PCDX in both injectable scaffold and microparticles (MPs) forms effectively evades FBR and provides slow release of antigens resulting in local enrichment of CD11c+ DCs at the MPs injection sites. DC cultured on PCDX exhibits strong immunogenic activation with high CD86, CD40, MHC-I/peptide complex. PCDX also generates DC with propensity in migration to lymph nodes, as well as antigen presentation to trigger both CD4+ and CD8+ arms of T-cell responses.Type: ApplicationFiled: October 7, 2024Publication date: April 10, 2025Inventors: Jin Teng CHUNG, Ying CHAU, Chi Ming Laurence LAU

Patent number: 10558509Abstract: Techniques are described for detecting anomalous behavior in program execution. In one example, a method includes logging occurrence of one or more key run time events during execution of a program. Each key run time event has a corresponding key run time event data structure associated with the program, and logging includes storing records associated with the key run time events, wherein each record is based on the key run time event data structure associated with the key run time event. The method further includes analyzing the records to determine if a current pattern of key run time events associated with the program during execution matches an expected pattern of key run time events and generating a security alert if the current pattern of key run time events does not match the expected pattern of key run time events for the program.Type: GrantFiled: February 13, 2019Date of Patent: February 11, 2020Assignee: International Business Machines CorporationInventors: Rachel E.
