San Diego BioMed would like to recognize Professor James Binley who has been given the honor of writing a perspective on a breakthrough paper by researchers at UPenn in the top journal, Science.

This paper describes a study in which preclinical models were infected by a chimeric virus that includes a mutated form of the HIV coat protein. Within a year of infection, most infections resulted in the hosts developing broadly neutralizing antibodies. This occurred by a series of mutations in the virus and the antibody response, so that the antibodies could rapidly zero in on a conserved site of vulnerability on HIV. This work is pivotal as it provides a detailed molecular template for researchers to develop a vaccine that could elicit similar antibodies in humans that could ward off HIV infection.

Congratulations to the joined effort of San Diego BioMed’s Marcondes Lab and their collaborators in the recent release of their publication titled, “Distinct Roles of Dopamine Receptors in HIV Latency Reversal in a Myeloid Cell Model.”

Stimulant drugs like methamphetamine elevate brain dopamine (DA) levels, which can reactivate latent HIV in myeloid brain cells — a key reservoir of the virus in people living with HIV. However, the specific receptors and pathways responsible have remained poorly defined. In this study, the Marcondes lab shows that two DA receptors, DRD1 and DRD4, independently increase HIV transcriptional activity in latently infected cells, but with surprisingly little overlap in the gene clusters, pathways, or upstream regulators they engage compared to DA itself. Instead, the two receptors share more in common with each other than with DA, suggesting cross-regulation between DRD1 and DRD4 signaling. Despite these mechanistic differences, convergent inflammatory and cell activation signatures emerged across all conditions, identifying a shared downstream consequence regardless of which receptor is engaged. These findings are relevant beyond stimulant use: they reveal that neuroimmune modulation of HIV latency in the brain is inherently multi-pathway and cannot be captured by studying single receptors or neurotransmitters in isolation, with direct implications for designing targeted interventions against the brain viral reservoir in HIV-associated neurocognitive disorders.

“Autosomal Allelic Inactivation: Variable Replication and Dosage Sensitivity,” is now available as a reviewed preprint in eLife!

In this latest study, the Gilbert lab contributed to a larger effort that explored why some genes are expressed more from one copy of a chromosome than the other.

Typically, you inherit two copies of genes, one from each parent, and both tend to be active to determine hereditary traits. In some cases, however, one copy may be active and the other silent. Based on this, the researchers identified the regions, called Inactivation/Stability Centers (I/SCs), that influence which gene copy is used in a cell and when each copy is duplicated during cell division. The choice of which copy is active appears to be random.

Because different cells may activate different gene copies, tissues can then become a patchwork of cells with slightly different gene activity. While this cellular diversity may be a normal part of development, it can also affect how genetic diseases appear.

If a person carries a harmful mutation in one copy of such a gene, the random silencing of the healthy copy in some cells could reduce the amount of functional gene product below what the body needs. The researchers found that many genes located within these regions are linked to conditions such as Parkinson's disease, Epilepsy, inherited deafness, and intellectual disabilities.

Overall, this work reveals a previously underappreciated layer of gene regulation in the human genome and suggests that random, cell-to-cell differences in gene activity may play an important role in human development and disease.

Congrats to the Gilbert lab and colleagues for their findings and hard work!

“Microhomology-mediated end joining acts directly on replication forks to repair single-ended double strand breaks,” is now available online!

When cells divide, they must copy their DNA so that the divided cells each receive a complete set of genetic instructions. During this process, the DNA-copying mechanisms can stall or break under what is called “replication stress,” which is common in cancer cells. These breaks, however, can be repaired so that the cell survives.

In this study, the Gilbert lab contributes to a larger effort as the researchers collaborate to examine that repair process called microhomology-mediated end joining (MMEJ). The researchers found that this repair pathway can act directly at the broken replication fork, working alongside another repair mechanism known as break-induced replication (BIR).

They also discovered that a protein called Polθ helps carry out this repair, while another key DNA damage response protein, ATR, can suppress it and instead promote the BIR pathway.

Importantly, the study found that blocking both ATR and Polθ at the same time strongly kills cancer cells experiencing high replication stress, while having much less effect on normal cells. This suggests a potential new strategy for developing targeted cancer therapies.

Great work by San Diego BioMed’s Gilbert lab and the whole team! We look forward to their continued discoveries!

Congratulations to Dr. Daniel Murin and the Murin Lab for their recent publication titled, “MINFLUX nanoscopy to study the NK cell immune synapse,” which is accessible as a book chapter in Methods of Cell Biology or on Elsevier.

San Diego BioMed’s Murin lab spotlights novel techniques in the fast-moving environment of biomedical research as it intersects with technological innovation.

Dr. Murin comments: “This work is a culmination of several months of effort to setup new methodology for studying natural killer (NK) cell biology using the cutting-edge technique of MINFLUX nanoscopy. We wanted to be able to see a protein named CD16a, which is responsible for inducing antibody dependent cellular cytotoxicity (ADCC), within immune synapses formed by NK cells. We anticipated the need for sub-10 nanometer localization precision to be able to detect individual proteins on the NK cell surface and therefore turned to MINFLUX nanoscopy to perform these studies. MINFLUX is the result of Nobel Prize winning work in super-resolution microscopy that enables scientists to label proteins with fluorophores that blink and then identify those proteins with up to single nanometer localization precision. Before we began this project, there were no protocols for utilizing the MINFLUX in the way required to study NK cell synapse structure. Therefore, Dr. Ross was able to pioneer a new methodology that enabled us to collect high quality single molecule data. The paper we have published as a book chapter in Methods in Cell Biology details this methodology and includes protocols for sample prep, data collection, and data analysis.

This is second paper published by the Murin Lab in less than a year and we are very proud of this accomplishment!”
