Welcome to the Battle: Triple Negative Breast Cancer Takes on a New Opponent!
Ah, triple negative breast cancer – the sneaky ninja of the cancer world! Not only does it have a name that sounds like it should be the title of a James Bond film, but it’s also notoriously difficult to treat. You see, this aggressive cancer has a devious little trick up its sleeve: it builds “molecular bridges.” And no, they aren’t offering tours or inviting you over for tea; they’re actively playing hide-and-seek with your immune system, making it look the other way while the cancer grows!
The Molecular Bridges: A Game of Dodgeball
Research, as delicate as a game of dodgeball and just as intense, shows that these cancer cells are sending out signals that prompt nearby immune cells to form these pesky bridges. Instead of getting an all-access pass to the party, your immune system gets hit with a “do not disturb” sign! This brilliant yet dastardly strategy strengthens the cancer’s hold on the body and helps it thrive – talk about a bad houseguest!
Thanks to the academic masters at Professor Idit Shachar’s lab, we’re finally getting a look behind the curtain. It turns out these tumors are difficult to treat not just because they’re clever evaders, but also because they’re crafty and know how to keep their safety nets strong!
Teamwork Makes the Dream Work: Weizmann and City of Hope
Now, enter the dynamic duo of the cancer research world: the Weizmann Institute and City of Hope. Together, they’ve embarked on a research quest, hunting down the role of CD84 (SLAMF5) – the protein that’s basically handing out bridge-building permits to cancer cells. When they’ve tested these maverick cancer cells on mice, they found that removing CD84 resulted in tumors that were smaller than they hoped for during a blackout sale!
This wasn’t just a lucky break; it led to an exciting discovery about directing therapy away from directly squashing cancer cells (which are tricky little rascals) and instead targeting their supportive environments. Think of it as going after the mobster’s lair instead of trying to catch a slippery henchman!
The Role of Immunosuppressive B Cells: The Good Undercover Agents?
Here’s where it gets more intriguing: these molecular bridges are not just party decorations; they’re enlisting B cells that serve as the cancer’s bodyguards! They unleash a suppressor protein that effectively says “Hey T cells, take a nap! Nothing to see here!” If T cells are supposed to be the brave knights charging into battle, they’ve been knocked out with a tranquilizer! The good news? Scientists are figuring out how to take away that power!
A Rosa Parks for Personalized Medicine
Professor Shachar and her sharp-minded squad are buzzing about the possibilities of this newly developed antibody! The plan isn’t just to tackle triple negative breast cancer; it’s like opening Pandora’s box for different cancers that use similar sneaky evasion tactics. Imagine a future where we personalize treatments based on individual characteristics! Each therapy could match the hospital gown – tailored just right, darling!
Here’s the kicker: most healthy cells don’t have high levels of CD84, so this antibody could serve as an exclusive VIP pass against the cancer cells without dragging innocent bystanders into the chaos like traditional chemo. Let’s be real: who doesn’t want to take fewer hits while kicking cancer to the curb?
A New Horizon: Hope Surfaces
So, what’s next in this epic saga of molecular warfare? Experts from around the globe are rallying around this breakthrough, proving that when it comes to cancer research, the stakes are high but the rewards can be extraordinary. By busting down those molecular bridges, scientists are crafting a new arsenal in the battle against one of the trickiest foes known to humanity.
Keep your eyes on the prize because this is just the beginning! Every study could pave the way for hope for many fighting similar battles. Now, let’s all raise a cup of tea (for good measure) to science and the brave ones ready to charge into battle for our health. Cheers!

This groundbreaking discovery paves the way for potentially revolutionary treatments for aggressive forms of cancer, particularly triple-negative breast cancer, by focusing on the intricate molecular mechanisms that promote tumor progression and survival.
The molecular bridges of cancer: a strategy for tumor survival
In a strikingly strategic manner akin to a tactical war, tumors associated with triple-negative breast cancer construct “molecular bridges” in their surrounding environment. This nefarious tactic effectively deceives the immune system, preventing it from mounting an attack against them. Researchers from Professor Idit Shachar’s advanced laboratory have demonstrated how these bridges fortify the tumor’s capacity to survive and thrive. This challenging type of cancer presents a formidable opponent due to its resilience and its evasiveness, making it one of the most perplexing targets in oncology.
The findings from this research, featured in the prestigious journal Cell Reports, detail the mechanisms by which cancer cells emit signals that induce nearby immune cells to construct these insidious “bridges.” The formation of these connections effectively obstructs the immune response, thereby accelerating tumor growth. Remarkably, by impeding the creation of these molecular bridges, the antibody developed by Weizmann scientists reinstates the immune system’s ability to combat cancer, achieving significant inhibition of tumor progression in preclinical studies using mice.
Breast cancer and its environment: a complex enemy
Historically, cancer treatments prioritized the destruction of cancerous cells directly; however, innovative research is increasingly highlighting the significance of the tumor’s microenvironment. In previous investigations, the dedicated team at Weizmann identified that certain blood cancers create analogous bridges via a protein known as CD84 (SLAMF5). This protein facilitates a bond between cancer cells and supportive immune cells, ultimately enhancing the tumor’s survival and proliferation capabilities.
The collaboration between Weizmann and City of Hope
While conducting studies on the most aggressive variant of breast cancer, researchers found elevated levels of CD84 present in the tumor microenvironment. This significant discovery emerged from a collaborative effort with the esteemed research center City of Hope in California, recognized as one of the leading cancer treatment facilities in the United States. Dr. Steven Rosen, a prominent figure at City of Hope, initiated the exploration of patient samples suffering from triple-negative breast cancer, a notably evasive form of cancer with currently limited treatment options.
Unfortunately, unlike other cancer types, triple-negative breast cancer lacks distinct external characteristics that facilitate easy identification. Consequently, the research team began investigating treatment alternatives that target the supportive microenvironment instead of focusing solely on the cancer cells themselves, representing a transformative and potentially more effective strategy.
The role of CD84 in the tumor microenvironment
Investigations conducted in Professor Shachar’s lab, spearheaded by doctoral student Stav Rabani, revealed that tumors from patients afflicted with triple-negative breast cancer exhibit conspicuously high levels of CD84. When these tumors were studied in genetically modified mice incapable of expressing this protein, researchers observed a notable reduction in tumor size.
This pivotal discovery prompted researchers to test an antibody previously shown to inhibit the formation of molecular bridges in blood cancer contexts. Trials conducted on mice with breast cancer demonstrated that Injections of the antibody, administered bi-weekly, significantly retarded tumor growth and, in certain instances, resulted in complete remission.
Immune cells and the cancer evasion strategy
CD84-driven molecular bridges facilitate the accumulation of immunosuppressive cells within the tumor microenvironment, thereby allowing cancer to evade the immune response and proliferate unchecked. In this context, regulatory B cells assume a critical role; these bridges induce B cells to produce a suppressor protein that inhibits T cell activity, the very cells tasked with attacking cancer. When this suppressor protein infiltrates the tumor microenvironment, it undermines T cell efficacy, thwarting their ability to obliterate the cancer cells.
A treatment with potential for personalization
Professor Shachar and her research team harbor optimism regarding the potential of this innovative antibody aimed at cells exhibiting elevated CD84 levels, thereby unlocking new therapeutic possibilities for a variety of tumors beyond merely those directly linked to the CD84 protein. This breakthrough is particularly significant in the realm of personalized medicine, where treatment regimens are designed to align with the unique characteristics of each patient.
Shachar underscores the fact that the majority of healthy cells do not express high levels of CD84, enhancing the specific and less invasive nature of this antibody. Unlike traditional treatment modalities, such as chemotherapy—which indiscriminately harms both healthy and malignant cells—this approach aspires to specifically target the tumor microenvironment, thereby reducing associated side effects.
New perspectives in cancer research
This notable advance has garnered significant interest from leading experts in the fields of immunology and molecular oncology. Esteemed professionals such as Professor Emine Gulsen Gunes, Dr. Martin Gunes, Dr. Aimin Li, and Professor Raju Pillai from the City of Hope, along with Bianca Pellegrino, Bar Lampert, and Dr. Keren David from the Weizmann Institute, are keenly observing the developments.
By obstructing these molecular bridges, scientists unveil a promising frontier in the battle against breast cancer, one of the most arduous and multi-faceted diseases to combat. Although research persists, the compelling findings from this dedicated team impart a glimmer of hope for innovative therapies targeting this and other cancer forms employing similar evasion strategies against the immune system.

H the unique characteristics of each patient’s cancer, offering a more tailored approach to therapy. By focusing on the supportive tumor microenvironment, this strategy may not only improve outcomes for patients with triple-negative breast cancer, but also extend to other cancer types exhibiting similar immune evasion mechanisms.
With this approach, researchers envision a future where treatments are not one-size-fits-all but rather customized to target the specific vulnerabilities of individual tumors. This could lead to more effective interventions that spare healthy tissues while maximizing the destruction of malignant cells.
The implications of this research could be far-reaching, representing a paradigm shift in how oncologists approach cancer treatment. As scientists continue to explore the impact of immune modulators and the interplay between tumors and their environments, the dream of personalized cancer therapy moves closer to reality.
