Environmental arsenic hijacks DDX5-mediated FANCA splicing to impair R-loops resolution and drive ovarian aging.

Arsenic, a widespread environmental toxicant, is increasingly implicated in female reproductive dysfunction. Long-term exposure to low concentrations of arsenic leads to diminished ovarian reserve. However, the mechanisms by which arsenic exposure accelerates ovarian aging remain unclear.

Generation of TIM3 inhibitory single-domain antibodies to boost the antitumor activity of chimeric antigen receptor T cells.

Targeting inhibitory immune checkpoint molecules has significantly altered cancer treatment regimens. T cell immunoglobulin and mucin domain 3 (TIM3) is one of the major inhibitory immune checkpoints expressed on T cells. Blocking the engagement of TIM3 and its inhibitory ligand galectin-9 may potentiate the effects of immunotherapy or overcome the adaptive resistance to the therapeutic blockade of programmed cell death protein 1, cytotoxic T-lymphocyte-associated protein 4, B- and T-lymphocyte attenuator and lymphocyte-activation gene 3, amongst others, as each of these immune checkpoints harbors unique properties that set it apart from the rest.
