These antibodies are like superheroes that can recognize and tag these disguised villains, sending a signal to the body’s immune system to swoop in and take them down.

Let’s dive into the specific malignancies where these antibodies are kicking cancer’s butt:

• Multiple Myeloma: This clever cancer hides in the bone marrow, but anti-CD38 antibodies aren’t afraid to go after it. They’ve shown amazing promise in clinical trials, leading to longer survival rates and fewer nasty side effects.

• Mantle Cell Lymphoma: This sly cancer attacks the body’s lymphatic system. But anti-CD38 antibodies are like the SWAT team, going in and unleashing a deadly attack on these cancerous cells.

• Amyloidosis: This sneaky disorder causes proteins to clump up in the body’s organs. Anti-CD38 antibodies are helping to unravel these clumps and improve organ function in patients with this challenging condition.

Mechanisms of Action: How Anti-CD38 Antibodies Fight Cancer

Picture this: the villainous cancer cells are like cunning ninjas, elusive and deadly. But they’ve met their match in anti-CD38 antibodies, the superheroic molecules that fight back with a triple punch of fury!

Punch 1: Complement-Mediated Cytotoxicity

It’s like calling in the cavalry! Anti-CD38 antibodies act as beacons, signaling the immune system’s “complement proteins” to swarm around cancer cells. These proteins poke holes in the cancer cells’ defenses, leaving them vulnerable to attack.

Punch 2: Antibody-Dependent Cellular Cytotoxicity (ADCC)

Cue the “NK cells,” the immune system’s natural assassins! Anti-CD38 antibodies tag cancer cells for these NK cells, which then rush in and unleash a barrage of deadly toxins, neutralizing the cancer cells’ evil plans.

Punch 3: Direct Apoptosis

Finally, anti-CD38 antibodies can trigger an internal self-destruction mechanism within cancer cells. It’s like a biochemical “kamikaze,” leading to the cancer cells’ untimely demise.
