V(D)J recombination generates the diverse B and T cell receptors essential for recognizing a wide array of antigens. This diversity arises from the combinatorial assembly of V(D)J genes and the junctional deletion and insertion of nucleotides. While previous in vitro studies have shown that microhomology-short stretches of sequence homology between gene ends-can bias the recombination process, the extent of microhomology's impact in vivo, particularly in humans, remains unknown.

Age at HIV acquisition may influence viral pathogenesis in infants, and yet infection timing (i.e. date of infection) is not always known.

To appropriately defend against a wide array of pathogens, humans somatically generate highly diverse repertoires of B cell and T cell receptors (BCRs and TCRs) through a random process called V(D)J recombination. Receptor diversity is achieved during this process through both the combinatorial assembly of V(D)J-genes and the junctional deletion and insertion of nucleotides. While the Artemis protein is often regarded as the main nuclease involved in V(D)J recombination, the exact mechanism of nucleotide trimming is not understood.

Article Synopsis
  • The study explores how prostate cancer evolves genetically due to treatments aimed at blocking androgen receptor (AR) signaling, highlighting the need for a deeper understanding of structural changes in the cancer genome.
  • Researchers analyzed 674 prostate cancer samples (531 localized and 143 metastatic) through whole genome and transcriptome sequencing to identify significant genetic alterations and structural variations.
  • They found unique genetic patterns in different stages of the disease, distinguishing 9 subclasses of metastatic castration-resistant prostate cancer (mCRPC) which relate to specific genetic traits and clinical outcomes, offering insights for potential targeted therapies.

Every T cell receptor (TCR) repertoire is shaped by a complex probabilistic tangle of genetically determined biases and immune exposures. T cells combine a random V(D)J recombination process with a selection process to generate highly diverse and functional TCRs. The extent to which an individual's genetic background is associated with their resulting TCR repertoire diversity has yet to be fully explored.

Hereditary sensory and autonomic neuropathy type III, or familial dysautonomia [FD; Online Mendelian Inheritance in Man (OMIM) 223900], affects the development and long-term viability of neurons in the peripheral nervous system (PNS) and retina. FD is caused by a point mutation in the gene that results in a tissue-specific reduction of the IKAP/ELP1 protein, a subunit of the Elongator complex. Hallmarks of the disease include vasomotor and cardiovascular instability and diminished pain and temperature sensation caused by reductions in sensory and autonomic neurons.
