Prefrontal cortex PACAP signaling: organization and role in stress regulation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Pituitary adenylate cyclase-activating polypeptide (PACAP) is an excitatory neuromodulatory peptide strongly implicated in nervous stress processing. Human polymorphism of the primary PACAP receptor (PAC1) is linked to psychiatric disorders, including posttraumatic stress disorder (PTSD). Prefrontal cortex PACAP signaling is associated with processing of traumatic stress and fear learning, suggesting a potential role in PTSD-related deficits. We used RNAscope to define the cellular location of PACAP and PAC1 in the infralimbic cortex (IL). Subsequent experiments used a pharmacological approach to assess the impact of IL PACAP infusion on behavioral and physiological stress response and fear memory. Adult male Sprague-Dawley rats were bilaterally microinjected with PACAP (1 ug) or vehicle into the IL, 30 minutes prior to forced swim test (FST). Blood was sampled at 15, 30, 60, and 120 minutes for analysis of hypothalamic pituitary adrenal (HPA) axis reactivity. Five days after, animals were tested in a 3-day passive avoidance paradigm with subsequent testing of fear retention two weeks later. We observed that PACAP is highly expressed in putative pyramidal neurons (identified by VGlut1 expression), while PAC1 is enriched in interneurons (identified by GAD). Pretreatment with PACAP increased active coping style in the FST, despite higher levels of ACTH and corticosterone. The treatment was also sufficient to cause an increase in anxiety-like behavior in a dark/light crossover test and enhanced retention of passive avoidance. Our data suggest that IL PACAP plays a role in driving stress responses and in processing of fear memories, likely mediated by inhibition of cortical drive.
