Beyond checkpoint inhibitors: the three generations of immunotherapy.

Anti-tumor immunotherapy was rediscovered and rejuvenated in the last two decades with the discovery of CTLA-4, PD-1 and PD-L1 and the roles in inhibiting immune function and tumor evasion of anti-tumor immune response. Following the approval of the first checkpoint inhibitor ipilimumab against CTLA-4 in melanoma in 2011, there has been a rapid development of tumor immunotherapy. Furthermore, additional positive and negative molecules among the T-cell regulatory systems have been identified that that function to fine tune the stimulatory or inhibitory immune cells and modulate their functions (checkpoint modulators).

Growth hormone (GH) secretion by the pituitary is regulated by stimulatory and inhibitory pathways such as growth hormone releasing hormone (GHRH) and somatostatin, respectively, being also modulated by different neurotransmitters acting at the hypothalamic/pituitary level. The pineal gland hormone melatonin regulates GH secretion in many mammals, including humans, although its role in modulating GH secretion has been debated. We describe the case of a young woman chronically taking melatonin for sleep disturbances, referring to her general practitioner for flushing that appeared just after starting melatonin intake.

Polymeric nanoparticles (NPs) are promising tools used for immunomodulation and drug delivery in various disease contexts. The interaction between NP surfaces and plasma-resident biomolecules results in the formation of a biomolecular corona, which varies patient-to-patient and as a function of disease state. This study investigates how the progression of acute systemic inflammatory disease influences NP corona compositions and the corresponding effects on innate immune cell interactions, phenotypes, and cytokine responses.

Human puberty is a dynamic biological process determined by the increase in the pulsatile secretion of GnRH triggered by distinct factors not fully understood. Current knowledge reveals fine tuning between an increase in stimulatory factors and a decrease in inhibitory factors, where genetic and epigenetic factors have been indicated as key players in the regulation of puberty onset by distinct lines of evidence. Central precocious puberty (CPP) results from the premature reactivation of pulsatile secretion of GnRH.
