The human body's immune defense relies on a complex array of mechanisms, including a network of over 30 plasma proteins known collectively as the complement system, which acts as a key surveillance and response system against pathogens.

Over 100,000 different types of proteins are estimated to exist in the human body, with many playing fundamental roles in immune defense and infection control. These versatile molecules are the powerhouses of immunity, operating through intricate mechanisms to identify, neutralize, and eliminate threats, demonstrating precisely how proteins protect against disease.

Did you know that thousands of different proteins are constantly at work inside your body? These microscopic powerhouses play a fundamental and multifaceted role in your immune system's ability to defend the body against countless threats.

According to a study published in *Communications Biology*, reducing dietary protein can boost the immune system's response against bacterial infections, highlighting a complex and direct relationship between protein intake and immune function. This means the answer to "does protein fight bacteria?" is a definitive yes, though the mechanisms are more intricate than simply consuming more protein.

The liquid portion of your blood, known as plasma, is comprised of about 7% proteins by volume. Among these are the 5 proteins in plasma that carry out vital functions such as regulating osmotic pressure, providing immunity, transporting molecules, and facilitating blood clotting.
