The roles of intraflagellar transport (IFT) protein 25 in mammalian signaling transduction and flagellogenesis.

Cilium, an organelle with a unique proteome and organization, protruding from the cell surface, generally serves as a force generator and signaling compartment. During ciliogenesis, ciliary proteins are synthesized in cytoplasm and transported into cilia by intraflagellar transport (IFT) particles, where the inner counterparts undergo reverse trafficking. The homeostasis of IFT plays a key role in cilial structure assembly and signaling transduction. Much progress has been made on the mechanisms and functions of IFT; however, recent studies have revealed the involvement of IFT particle subunits in organogenesis and spermatogenesis. In this review, we discuss new concepts concerning the molecular functions of IFT protein IFT25 and how its interactions with other IFT particle subunits are involved in mammalian development and fertility.

Utilizing Alternative Testing Technology for Human Immunodeficiency Virus (HIV) in the COVID era.

PURPOSE OF REVIEW: With the onset of the Coronavirus disease 2019 (COVID-19) pandemic, in-person human immunodeficiency virus (HIV) testing is no longer easily accessible. Therefore, alternative testing technologies must be considered and implemented on a large scale to continue prevention efforts. This review seeks to describe the benefits of utilizing at-home HIV testing technologies, traditionally deemed an alternative form of testing. RECENT FINDINGS: Utilizing at-home testing technology during the COVID-19 pandemic overcomes novel and previously identified barriers to HIV testing. SUMMARY: Ensuring access to HIV testing is imperative to long-term prevention goals. With the Ending the HIV Epidemic (EHE) initiative in the USA targeting achievement by 2030, obstacles to HIV testing must be addressed to ensure its success. Implementing alternative testing technology more broadly allows for continued prevention efforts for HIV in light of COVID era restrictions.
