Abstract:
Lymphoid cells in decidualized uterine endometrium in early human pregnancy may be essential for successful implantation and placentation. Endometrial granulocytes are prominent in early pregnancy decidua and express some T-cell associated surface antigens (CD2+, CD7+), but little is known of their function. We report the unusually intense binding of the natural-killer (NK) cell marker NKH1 to endometrial granulocytes, which contrasts with their lack of reactivity with other NK-cell markers.

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
