• Citrus OGD2, Iron, and Ferroptosis in Canker

  2026-09-03

  The reference study identifies CmOGD2 as a central regulator of citron resistance to citrus canker, linking iron uptake and ROS accumulation with likely ferroptotic cell death. It also reveals a feedback circuit involving CmENO2 and CmZAT10.1 and shows how the Xcc effector pthA4 may disrupt this circuit, providing a mechanistic framework for studying iron-dependent plant immunity.

• Dietary Arachidonic Acid and Humoral Immunity

  2026-09-02

  The reference study shows that dietary arachidonic acid can accelerate rabies vaccine-induced neutralizing antibody responses in mice and human volunteers. Its mechanistic contribution is the identification of a lymph-node lipid pathway in which prostaglandin I2, cAMP-PKA signaling, CD86, and activation-induced cytidine deaminase connect dietary lipid metabolism with germinal-center B-cell maturation.

• N-Formimidoyl Thienamycin vs New β-Lactams

  2026-09-01

  The 1982 study benchmarked N-formimidoyl thienamycin (MK0787) against several recently developed β-lactam antibiotics in resistant clinical isolates. Its central finding was a broad, largely bactericidal activity profile against gram-negative organisms, including Pseudomonas aeruginosa and Acinetobacter, with activity that was comparatively less affected by β-lactamase production.
