Complications of Long-Acting Reversible Contraceptive Modalities.
Pediatric emergency care
2023; 39 (6): 443-449
Abstract
Long-acting reversible contraception has risen in popularity in recent decades and is becoming one of the more common modalities of contraception in the United States, with a growing adolescent population among its users. The 2 modalities of long-acting reversible contraception-intrauterine devices and subcutaneous hormonal implants/etonogestrel implants (referred to as Nexplanon in the US)-are beneficial for their excellent effectiveness, ease of use, and safety profile. This article reviews the pharmacology of these modalities, common complications and their presentations, and the initial evaluation and management in the pediatric emergency department setting. Where applicable, attention will be paid to problems unique to the adolescent population.

MARCH1 protects the lipid raft and tetraspanin web from MHCII proteotoxicity in dendritic cells.
The Journal of cell biology
2018; 217 (4): 1395-1410
Abstract
Dendritic cells (DCs) produce major histocompatibility complex II (MHCII) in large amounts to function as professional antigen presenting cells. Paradoxically, DCs also ubiquitinate and degrade MHCII in a constitutive manner. Mice deficient in the MHCII-ubiquitinating enzyme membrane-anchored RING-CH1, or the ubiquitin-acceptor lysine of MHCII, exhibit a substantial reduction in the number of regulatory T (Treg) cells, but the underlying mechanism was unclear. Here we report that ubiquitin-dependent MHCII turnover is critical to maintain homeostasis of lipid rafts and the tetraspanin web in DCs. Lack of MHCII ubiquitination results in the accumulation of excessive quantities of MHCII in the plasma membrane, and the resulting disruption to lipid rafts and the tetraspanin web leads to significant impairment in the ability of DCs to engage and activate thymocytes for Treg cell differentiation. Thus, ubiquitin-dependent MHCII turnover represents a novel quality-control mechanism by which DCs maintain homeostasis of membrane domains that support DC's Treg cell-selecting function.
