Auxin regulates the transcription of auxin-responsive genes by the TIR1/AFBs-Aux/IAA-ARF signaling pathway, and in this way facilitates plant growth and development. However, rapid, nontranscriptional responses to auxin that cannot be explained by this pathway have been reported. In this review, we focus on several examples of rapid auxin responses (1) the triggering of changes in plasma membrane potential in various plant species and tissues, (2) inhibition of root growth, which also correlates with membrane potential changes, cytosolic Ca2+ spikes, and a rise of apoplastic pH, (3) the influence on endomembrane trafficking of PIN proteins and other membrane cargoes, and (4) activation of ROPs (Rho of plants) and their downstream effectors such as the cytoskeleton or vesicle trafficking. In most cases, the signaling pathway triggering the response is poorly understood. A role for the TIR1/AFBs in rapid root growth regulation is emerging, as well as the involvement of transmembrane kinases (TMKs) in the activation of ROPs. We discuss similarities and differences among these rapid responses and focus on their physiological significance, which remains an enigma in most cases.The generation of effective adaptive T-cell memory is a cardinal feature of the adaptive immune system. The establishment of protective T-cell immunity requires the differentiation of CD8+ T cells from a naive state to one where pathogen-specific memory CD8+ T cells are capable of responding to a secondary infection more rapidly and robustly without the need for further differentiation. The study of factors that determine the fate of activated CD8+ T cells into either effector or memory subsets has a long history. The advent of new technologies is now providing new insights into how epigenetic regulation not only impacts acquisition and maintenance of effector function, but also the maintenance of the quiescent yet primed memory state. There is growing appreciation that rather than distinct subsets, memory T-cell populations may reflect different points on a spectrum between the starting naive T-cell population and a terminally differentiated effector CD8+ T-cell population. Interestingly, there is growing evidence that the molecular mechanisms that underpin the rapid effector function of memory T cells are also observed in innate immune cells such as macrophages and natural killer (NK) cells. This raises an interesting hypothesis that the memory/effector T-cell state represents a default innate-like response to antigen recognition, and that it is the naive state that is the defining feature of adaptive immunity. These issues are discussed.
Insulin-like growth factor-1 (IGF-1) has been implicated in fetal and early-life growth and development of type 2 diabetes (T2D). We aimed to examine the interaction between circulating IGF-1 and birth weight in relation to risk of T2D.

We included 181 090 adults, aged 39-70 years in the UK Biobank Study, who were free of diabetes or major cardiovascular diseases at baseline. Serum IGF-1 levels were determined using chemiluminescent immunoassay method. Birth weight was self-reported; a Genetic Risk Score (GRS) was calculated to define the genetically determined birth weight. The outcome was the incidence of T2D.

We identified 3299 incident T2D cases over an average of 9.9 years of follow-up. Among the participants with birth weight of ≥2.5 kg, IGF-1 levels were inversely associated with T2D risk in a dose-dependent manner (p
trend<0.001). In contrast, the association was not significant among those with birth weight of <2.5 kg (p-interaction=0.001). The GRS of birth weight did not interact with IGF-1 levels on T2D risk.

Our results indicate that birth weight significantly modifies the relation between adulthood levels of circulating IGF-1 and the risk of T2D. Our findings highlight the importance of early-life risk factors in the development of the lifecourse prevention strategies targeting IGF-1 and T2D.

Here, we studied oncogenic KIT, which drives gastrointestinal stromal tumor (GIST), the most common sarcoma. Using mouse models of GIST, we found that KIT inhibition reduced type I IFN production and signaling, which downregulated tumor MHC class I expression. Absence of type I IFN signaling increased tumor size, in part due to CD8+ T-cell impairment. Oncogenic KIT was required for GIST type I IFN signal transduction via STAT1. In human GIST cell lines and surgical specimens, type I IFN signaling contributed to human lymphocyte antigen class I expression and correlated with tumor immunogenicity. Augmenting the type I IFN response partially compensated for the immunosuppressive effects of KIT inhibition. Thus, KIT signaling contributes to type I IFN signaling, whereas KIT inhibition attenuates tumor immunogenicity and is partly rescued by innate immune stimulation.See related Spotlight on p. 489.Post-transplant lymphoproliferative disorder (PTLD) of the oesophagus is a rare complication of solid organ transplant that requires a high index of suspicion to diagnose. selleck inhibitor A literature review conducted on Ovid Medline database retrieved 24 articles, among which five previous cases of oesophageal PTLD were identified. Development of oesophageal strictures related to PTLD has not been reported in the literature. We report a case of oesophageal PTLD following lung transplant, presenting with extensive, circumferential ulceration in the oesophagus. PTLD was successfully treated with chemotherapy but subsequently, this patient developed a severe oesophageal stricture at the site of her PTLD. She presented with an episode of food bolus impaction requiring endoscopic retrieval. In the following years, our patient required multiple endoscopic dilatations of this PTLD-related oesophageal stricture.
