CD4 T-cell aging exacerbates neuroinflammation in a late-onset mouse model of amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is an adult-onset progressive neurodegenerative disorder characterized by the loss of upper and lower motor neurons in the brain and spinal cord. Accumulating evidence suggests that ALS is not solely a neuronal cell- or brain tissue-autonomous disease and that neuroinflammation plays a key role in disease progression. Furthermore, whereas both CD4 and CD8 T cells were observed in spinal cords of ALS patients and in mouse models of the disease, their role in the neuroinflammatory process, especially considering their functional changes with age, is not fully explored.

An optimized protocol for the retroviral transduction of mouse CD4 T cells.

Transduction of primary T cells has become prominent with the introduction of chimeric antigen receptor T-cell therapy. Although there are many protocols for the transduction of human T cells, it remains a challenge to transduce murine T cells. We present an optimized protocol for the retroviral transduction of murine CD4 T cells, which overcomes major challenges including large-scale production and long-term culturing of transduced cells.

CPAP3 proteins in the mineralized cuticle of a decapod crustacean.

The pancrustacean theory groups crustaceans and hexapods (once thought to comprise separate clades within the Arthropoda) into a single clade. A key feature common to all pancrustaceans is their chitinous exoskeleton, with a major contribution by cuticular proteins. Among these, are the CPAP3's, a family of cuticular proteins, first identified in the hexapod Drosophila melanogaster and characterized by an N-terminal signaling peptide and three chitin-binding domains.
