Annual Conference of the Society of General Physiologists (SGP) at Woods Hole, MA, USA. The topic is Ion Channels and Transporters in Immunity. The conference is a hybrid meeting with some speakers and attendees attending in-person (only from the US because of the travel ban still in place) and others participating ONLINE. Registration for online (virtual) participation is open and information can be found on our website at https://www.sgp2021.com/ The fact that the meeting is a hybrid will make it easy for people curious about the topic but not be able to attend the conference in person to participate.
