Antibodies, essential components of adaptive immunity, derive their remarkable diversity primarily from V(D)J gene rearrangements, particularly within the heavy chain complementarity-determining region 3 (CDR-H3) where D genes play a major role. Traditionally, D genes were thought to recombine only in the forward direction, despite having identical recombination signal sequences (12 base pair spacers) at both ends. This observation led us to question whether these symmetrical sequences might enable bidirectional recombination.

Nanozymes play a pivotal role in mitigating excessive oxidative stress, however, determining their specific enzyme-mimicking activities for intracellular free radical scavenging is challenging due to endo-lysosomal entrapment. In this study, we employ a genetic engineering strategy to generate ionizable ferritin nanocages (iFTn), enabling their escape from endo-lysosomes and entry into the cytoplasm. Specifically, ionizable repeated Histidine-Histidine-Glutamic acid (9HE) sequences are genetically incorporated into the outer surface of human heavy chain FTn, followed by the assembly of various chain-like nanostructures via a two-armed polyethylene glycol (PEG).

Chronic lymphocytic leukemia (CLL) is a less common hematological malignancy in Indian people. It accounts for less than 5% of all leukemias. Information on genomic alteration in CLL is limited immunoglobulin heavy-chain variable region (IGHV) mutational status is considered the most reliable prognostic marker.
