The integrated stress response promotes immune evasion through lipocalin 2 - Nature
The transcription factor ATF4 and its effector lipocalin 2 (LCN2) have a key role in immune evasion and tumour progression, and targeting the ATF4–LCN2 axis might provide a way to treat several types of solid tumour by increasing anti-cancer immunity.

🌅 Several studies have suggested checkpoint inhibitors dosed AM may be assoc w/ improved outcomes- but strong risk of confounding. Out now in #JCOOP: review of literature & discussion of how practices could actually implement this. Suspect will be very dependent on local AM traffic!
Fig 2. Constraints related to the patient, the pharmacy, and the outpatient infusion centers to be taken into account when concentrating outpatient ICI administrations in a stipulated time window in the morning. ICI, immune checkpoint inhibitor.

Pharmacy constraints: physiochemical stability, risk of waste. Patient: distance home-hospital, diurnal preference. Day unit: priority rankings, long multi drug regimens.Proposed Action

We propose the following approaches to make early ToDA of ICI feasible in daily routine practice:
•	
ASSESS: establish a nurse-led telephone assessment on the eve of ICI administration with full blood work-up available to confirm clinical and biologic permissiveness to ICI treatment;
•	
AVOID (as far as possible and according to the habits of each center): do not schedule medical consultation and ICI treatment on the same day to reduce risks of delays in treatment administration (prefer teleconsultations the day before treatment for patients living far from the center);
•	
ALWAYS administer ICI first when in combination with IV chemotherapy or other agents, unless reverse sequencing is recommended;
•	
ALLOCATE: prioritize two or three ICI mornings per week and save the remaining two or three mornings for long-term combination treatments not including ICIs;
•	
ANTICIPATE: whenever possible, cytotoxic reconstruction units could prepare ICIs in the evening of the eve so that they are ready to be administered early on the following morning.

Macrophages can eliminate cancer cells through phagocytosis, which is tightly regulated through inhibition and activation of various phagocytic receptors.
